There should be an undo button, though. Especially without a brush size preview.
It’s really tedious to do it manually and something like OpenCV shines.
We found a repo [1] with python code that automatically detects and blurs faces. This script was one of many, except it had a very high accuracy. Over 90%.
Removing exif data is a great idea.
[1] github.com/telesoho/faceblur
$ exiftool -all= foo.jpg
And even better, save image first as .bmp or other format that doesn’t support metadata. Then reload and convert to jpeg, and run the exiftool on this image.

I can see some diligent prosecutors going back and looking at data to gather evidence.
Anonymizing photos of the violent ones is therefore likely to support their actions by making accountability less likely. To scrub ethically, limit it to the non-violent protestors. To support non-violence, better to help identify the violent people -- police or civilian -- the opposite of anonymizing them.
Perhaps it’s better to remove the section of photo with a person’s face instead? Or draw a shape over their face and flatten the image? It seems to me as long as the pixels are there the identifying data is there for anyone willing to spend the time and effort to find it.
Edit: Apparently it was interpol, not the US government. I can't find the reddit thread but here's a NYT article with the photo: https://thelede.blogs.nytimes.com/2007/10/08/interpol-untwir...
everything you said was good except this. google is not your (or the protesters') friend.
This depends a lot on the implementation details. If you blur an image using arbitrary-precision real numbers, then blurring is invertible. If you add a bit of random noise, or quantize your pixels into a finite-precision data type, then it becomes essentially one-way, and you cannot recover the original image.

In a situation where police feel justified to kill extra-judicially over a possibly fake 20 dollar bill, what hope do we have that protesters won't be targeted in unfair ways? Or worse, that organizers won't be hunted down like animals and murdered like in Furguson? It would be unethical to not do everything in your power to protect those in this position.
secondly how do you plan to identify violent vs non-violent protesters from a static image? How would you find their identity afterwards? There is overwhelming evidence to suggest these methods are at best ineffective and at worst racist, and in either case will lead to innocent people being charged.

In the case of upscaling an image, deconvolution involves looking for images which, when scaled down, resemble the original image being upscaled. That kind of pre-image approach can be applied to blur as well (if the blur process is deterministic).
I'm not sure I follow. Did he say "enhance" at any point during the process?
Other things are external to the EXIF but could be combined with it. The sequence numbers in the filenames are the most obvious signal. The precise number of megapixels of the image might also tell you what sensor was used -- so maybe an anonymizer should resample the image to a new size.
I guess these seem unlikely to be investigated, but then again nobody initially thought that telling every web server what fonts you have installed on your machine would be used against you, or that the existence of "Do Not Track" would make browsers easier to track. It just depends on how much it's worth to someone to write this stuff once -- then it's free for all future uses.
I just looked at https://en.wikipedia.org/wiki/Exif and there are lots of interesting possibilities.
Edit: For those downvoting, is there a problem with considering this possibility? I think it's incredibly unlikely, but ignoring black swans can one day come back to bite you. Ideally, everyone should be aware of the theories out there, however ludicrous, on the off chance that they are correct and require critical and swift action.

From my time in Portland, working at the courthouse as a court clerk during the Occupy movement, when hundreds of transient “protesters” camped out in the park, it is not surprising that some of those folks would OD or end up dead for reasons entirely not related to protesting but instead related to their unfortunate life circumstances. I do not know if the same is true of Ferguson, but the article does not seem to provide any evidence of calculated retaliation against protesters.
Reference: https://help.github.com/en/github/working-with-github-pages/...
I would pixelate the faces to be just 4x4 giant pixels. It destroys nearly as much information as blacking them out while still not disrupting the image too much
That can't be done with a blur. In a blur, pixels are merged or averaged together and information is lost. In some cases you could sharpen it a little, but it's still not going to be as good as the original image. In a really good blur, even the best sharpen algorithm isn't going to give you something that looks like an identifiable face.
that's exactly what the murderers want to achieve
If you want to make sure the actual, original image gets stored safely on another device automatically, use SyncThing or Resilio Sync.
It is better that ten innocent persons suffer than that one guilty escape.
-- Bizzaro William BlackstoneThe thing is people are already being held accountable for their skin tone, and the likelihood of changing your behavior when you have lived your entire life in an environment of constant oppression for fear of being identified in a protest is marginal, specially during catharsis, otherwise you wouldn't see for instance people burning police cars in front of a camera.
Keep in mind also that many (most?) of these "violent protestors" are simply reacting against violent cops in a power trip. I can't say I wouldn't react violently against a cop intentionally running over me and others with its SUV, but I can say that I would be thankful if my face was anonymized no matter how I reacted.

That contains as much conspiracy as "somebody is hunting down the protestors".
There are simpler possible explanations, I believe, e.g. people who join (or organize) riots are usually not the stable boring kind that live long, predictable lives full of planning and quiet afternoons. Drugs, crime, violence and mental health issues are probably more prevalent in that group than in the general population.
Is this more or less than the number of attendees we would expect to die based on Ferguson homicide rates and approximations of the number of attendees? I couldn't find that in the article.
Also, what's the theory that this isn't a coincidence? The police are murdering random protestors for some reason?
The short explanation is blurs are kernels that spread a pixel's value across other pixels, so knowing this, you can treat blurred pixel values as a system of equations to solve.
Is it because people are committing more crime than the original offense?
Twitter often shows geodata for users, but I think that's app-based and not derived from photo uploads.
Sometimes the "other side of the story" (as White Supremacists would say) does NOT need to be heard. Not now.

"Crawford was found shot to death Thursday night in his car, just like activist Darren Seals in 2016 and protester DeAndre Joshua the night of the Ferguson verdict in 2014. The latter two had gunshot wounds to the head and their cars were lit on fire. Crawford, it is believed by police, shot himself in the back seat of his car either in an attempted suicide or by accident."
It could be useful to protect people from relatiation under an authoritarian government, such as in Hong Kong. I dislike the idea of a government using mass automatic identification, that could be used again by authoritarians for terrible goals. I also dislike the idea of the opposite and using automatic anonymizing to protect criminals during riots. We're probably going to keep seeing an arms race in this, with good and bad actors on all sides.
I'd be careful with that assumption. The only thing that really loses information is the discretization back into 0-255 range, and that naturally loses very little information.
If you consider the pixels as a large vector of values, you're effectively multiplying it by a matrix (plus discretization afterwards). If that matrix has (near) full rank, you can restore (close to) all the information.
Consider an grayscale image with two pixels a = 10, b = 20. I apply a blur that transfers 10% of each pixel to the other one. I end up with 11, 19. I'm left with the information 0.9 a + 0.1 b = 11, 0.1 a + 0.9 b = 19. Clearly this system can be solved uniquely. Or equivalently, the blur matrix (and I don't mean the kernel but the full blur operation matrix) is [[ 0.9 0.1 ] [ 0.1 0.9]], which has full rank and is thus invertible.
You'd be surprised at the amount of image detail that can be recovered by filtering when the original distortion function is known. See also https://en.wikipedia.org/wiki/Deconvolution and the lower half of that page's "See also" links section.

Peaceful protest is being squashed and de-legitimized. This is the flowering of fascism.
Good. Black people factually live under an authoritarian regime in the US.
There are also a few that do face detection and blur on the AppStore.
Technically you are correct - you cannot recover the exact original image. The same is the true for saving an image as JPEG. But the question at hand is whether you can still recognize faces, not whether you can restore a byte-for-byte of the original. And whether JPEG or blurring, the answer is generally "yes".
It does depend on the implementation (and whether you know the implementation) how close you can get.
1) The code, for now, runs locally. This is good. To avoid the possibility of the code being tampered with at a later day (for example, it could be modified to send copies of the image to a server), download the webpage and use the saved copy, not the live copy.
2) Do not use the blur functionality. For maximum privacy, this should be removed from the app entirely. There are _a lot_ of forensic methods to reverse blur techniques.
3) Be weary of other things in the photograph that might identify someone: reflections, shadows, so on.
4) Really a subset of 2 and 3, but be aware that blocking out faces is often times not sufficient to anonymise the subject in the photo. Identifying marks like tattoos, or even something as basic as the shoes they are wearing, can be used to identify the target.
Any examples? You can't reverse it if the data is gone.
This is NOT true, at least for the "original" setting. Upload an image, download it again - the checksums are identical.
If you modify the time/date or add comments within Google Photos, that new information is kept in a .json file instead of the exif data, but Google NEVER modifies the original photo if you select "original" quality.
Showing the face of a protestor smashing in a window will not lead to that protestor being brought to court and handed a sentence for community service, a fine, or some light jail time. It will lead to extrajudicial retaliation and possibly death.
Again, it would be nice if that weren’t the case and we could trust law enforcement to behave appropriately. But given that they and their supporters are known to hunt down and kill people who protest against them, we cannot in good conscience make it easier for them to do so.
If we are to trust the cops again, they need to show us they are worthy of trust. And they sure aren’t doing that right now.
That's the problem - the data you think is gone isn't gone. High frequencies are gone.... but you left all the low frequencies, didn't you? You can read a face from the low frequencies.
Then again, maybe groups of people can be associated together, and a poor match is good enough given other clues.
So, much better to be safe than sorry.
I'm not sure if I had a particular good point to make, other than that blurring does remove information that cannot easily be reversed. You can probably make very convincing reconstructions, but they might not look like the original person.
Still, I would hope that as police are investigated they are held to a high standard of behavior. They do after all have a near monopoly on the lawful use of violence.
What I've seen in the past 2 days is that the police are doubling down on being oppressors, not public servants. I expect it to get much worse before it (possibly) gets better. And it may not get better.
What? I’m not sure what country you’re talking about. Are you talking about America? Our police find rioters and shoot them dead in the street?
Man, I feel like you live in a different country than me, and I’ve lived in 9 states in every part of the country, and across nearly every income brackets (save extreme poverty or extreme wealth) and feel like your perspective is so disconnected from reality.
Who is getting away with what? They are under arrest right now. Or do you want them dragged through the streets?
I nearly always scale+compress photos that leave my possession, and usually using convert, so adding -strip is a nice streamlined way of doing all at once.
diminished in power.
It's only gone if it goes below the quantization threshold. Depends on the filter.
This is the country you live in, if you want ignore that fact its on you.
Nah. They would never do anything like that.
As everyone knows, all police are paragons of moral excellence in every country in the world at all times.
Governments have definitely never, ever gone after innocent protesters.
</sarcasm>
Yeah, white America. We call it "fascism" when that gets ruled the same way black America always has been.
But instead, "reverse" is being used here to mean something like analyze or to apply countermeasures to defeat the obfuscation.

i.e. how skewed are different professions w.r.t. morals?
Do you think lawyers are worse? Politicians? The Media? Where do police fit into this spectrum?

Would you like to provide an example of someone being killed for smashing a window?
I am aware that a number of african americans have been unjustly killed by police. That is a different claim than african americans are systematically oppressed by the US government.
For instance, compare what is happening in the US to a real authoritarian regime such as the USSR. The government made millions of innocent civilians disappear into the gulags en masse. Try to imagine even the hint of due process, let alone rioting and protests, within that regime.
Or compare what is happening here vs what is happening in China. The CCP places millions of Uighurs into concentration camps for no reason. In the US, we have thousands rioting violently in the streets, and I suspect the majority of the rioters will see little to no consequences for their actions.
One of the four officers is charged.
With a lesser charge than some are calling for (third-degree instead of first-degree murder).
I don't think the other three officers are under arrest right now. Some people regard them as involved and getting off too lightly so far.
With power comes a responsibilty to be better than others, and if that's not something you can count on, which it isn't, we need to protect others.
It’s probably also worth asking: when have violent protests ever helped the cause?
I think that the violence of the protests helped to get Derek Chauvin arrested. But I’m not sure that continued violence will help the broader movement.
Was the police violence worse during the time of the civil rights? Were the protesters ever violent or turn to rioting?
What would Dr King say about the protests?
What percentage of young people will die in a given year?
What percentage of those will happen to be community organizers?
What percentage of those will die by being shot in the head in a car that was then set on fire to annihilate forensic evidence?
Doesn't take too many steps out to get into the realm of zero percent probability that this is random chance
One method is the Lucy-Richardson deconvolution [1], which is an iterative algorithm, and here [2] is the best practical example I could find right away. Unfortunately the text is not in English, but the illustrations and formulae might be enough to give some intuition of the process.

This is really not true. The protests turned quickly into riots and the more heavy-handed police tactics literally started only days later.
The rioters burnt down a police station for gosh sakes.
There are no 'protetors' clashing with police in a violent way. I think decent folks move on after curfew.
It's the adventure-seeking rabble, those out for some photos, who want to see the action first hand, who might want to light something in fire. The people not dispersing at curfew I don't think are ideological or protesters in any sense of the word. It's just youth in antagonism for every and all reasons, as old as time.
I live in Portland, Oregon now. Without going into too many details, we have an expensive pension program. Many feel that the pension program is too generous, and there has been a lot of thought put into how we can fully fund both pensions and everything else. Last year there was a bill in the Oregon Senate (SB1049) that proposed some modest changes to how pensions work. It passed with bipartisan support, and the public unions went nuts. They said they'd never support a candidate who voted for SB1049.
Last month we had our primaries. The most important primary was the Democratic primary for the Oregon Secretary of State. If the governor were to step down for any reason (to take a cabinet position in the Biden administration, for example), the SOS becomes governor. Someone who opposed SB1049 joined the race at the last minute, got over half a million dollars of union money, outspent her candidate, and won the election.
This is just one of many examples. Even though the unions are only spending a couple of million dollars per year in Oregon, they're really smart about it, and as such, they get what they want. In the Secretary of State race they hit a home run. For half a million dollars, they pushed their preferred candidate through and sent a message that if you oppose them in any way, it will be a career limiting move.
The reason I mentioned that is because I think it is a good contrast to what we're seeing today. With smart leadership, we would have a better chance of solving this problem. But people are enraged and not thinking clearly. And there's no reason to believe that these riots are going to be more successful than the Baltimore riots, the Ferguson riots, the Oakland riots, or even the Rodney King riots.
Protest turned to riots, literally burning down police stations. Police action wasn't until much later, and they were perfectly fine with the daytime, civil unrest. During the evening, the 'protestors' went home and the agitators came out to fight police, and that's that.
When people are looting every store on a street, the police have no choice but to physically move in. There are very few options for anyone at that point.
If you’d like to have a smooth looking censored image you can then blur the mosaic result to have a smooth transition between the censored and original image.
If you simply blur or simply downsample there’s a significant ability to recover data or iterate over data to recover likely inputs. Other posts have discussed deconvolution, but think of a downsample as a hash - you can build a rainbow table of inputs, easily for numbers, with more difficulty for faces. If you have a limited pool of “suspects” this technique can work well. Just as with hashing, you should add a salt to the image before downsampling or blurring to make recovery of the original input more difficult. In this case the “salt” is random noise.
All I was really concerned about was getting rid of metadata tied to my phone.
So, at least in my town, it looks a lot like violent protests of the sort you decry do help. Certainly nothing else has done as well.
I'd caution against implying that this is a choice at all. It's not as if 15 times as many are 'choosing' to murder because of the colour of their skin.
That's why I'm glad this fact was omitted - it's not hard to imagine how it might be misinterpreted or exploited.
How about replace each face with a "this is not a person" AI generated face, then blur+mosaic. Or just a non-person face using a deepfake system that matches the facial expression?

If he was charged with first degree murder, he would walk if the high bar was not met.
For the record I agree with you, I'm just saying strategically it is a smarter move to ensure he is convicted for his crimes
By contrast, nothing will bring back George Floyd, let alone the countless black people afflicted by police brutality that weren't caught on camera. With millions still unemployed and a sense that society has left so many behind, COVID in the US was a powder keg looking for a match, and a breakdown of order shouldnt really be unexpected.

One was "active", one sent tear gas back at police, one livestreamed parts of the protest, and one's mother was in the protest.
The first two people, who were shot in their cars, I didn't see the extent of their involvement.
How many were involved at this level or higher? Tens of thousands? How many should we expect to die of murder, suicide, and drug overdose, and how many have?
What is the theory explaining this? Do you think there is a group murdering Ferguson protestors after the fact?
Nyet, comrade. My points were perfectly valid and to not acknowledge them is willful ignorance at best.
Black bloc and others are a problem but that actually feeds into what the authorities want, which is to completely suppress protest and civil disobedience.
Challenge: explain away the arrest of compliant CNN reporters on live tv, as well as the intentional targeting of reporters elsewhere (with rubber bullets), and last, but very much not least, the police shooting people in their yards for the act of filming them.
Only responding to this part. I've seen enough people get dox'd on the internet from static photos that I continue to be impressed each time by the skill of volunteer/angry people on <internet forum>
Some agitators are anti-government. Others are full on anarchists. Others want to bait people into race wars (a la the Turner Diaries, cited by white nationalist mass shooters and the Oklahoma City bomber).

Some of them are. But having to claim on insurance is an expensive proposition that eats into profit margins (which is extra difficult in the middle of a worldwide depression).

Most companies aren't multinational megacorps in high profit businesses.
I drove through South Central Los Angeles about 1 year after the Rodney King riots. I don't know what proportion of the businesses were rebuilt, but it was pretty clearly that many of the buildings hasn't been rebuilt. Large scale building damage takes a LONG time to rebuild and probably means the business can't run until it's done.
In all these riot situations, it is portrayed as the poor sticking it to the rich, who presumably are using the police to oppress the poor. But I suspect that in reality it is mostly the poor becoming even more downtrodden by the criminal elements, and the rich remain unaffected. Perhaps the rich even profit a bit from what happens, such as politicians winning more government money to "help with all the troubles".
The problem is converting that into something tangible that furthers their goals.
The practical effect is that if you're accused of being a member of "antifa" there's no coherent way to demonstrate you aren't, and certainly people opposed to fascism, whether or not they themselves identify with the label, are going to get accused of being "antifa."
(Also, to be clear on the news, he simply said that he intends to do this in a tweet - even if it were a coherent thing to do, there is no procedure for designating domestic groups as terrorist organizations.)
I even saw a video where one of them killed a guy while three others watched.
It's not required that the police be peaceful, only the protesters.
“…it is not enough for me to stand before you tonight and condemn riots. It would be morally irresponsible for me to do that without, at the same time, condemning the contingent, intolerable conditions that exist in our society. These conditions are the things that cause individuals to feel that they have no other alternative than to engage in violent rebellions to get attention. And I must say tonight that a riot is the language of the unheard. And what is it America has failed to hear?…It has failed to hear that the promises of freedom and justice have not been met. And it has failed to hear that large segments of white society are more concerned about tranquility and the status quo than about justice and humanity.” (“The Other America,” 1968).

He would understand. He would probably be out there. He might try to be a calming influence—or he might act as a street medic. He might have turned as militant as Malcolm X over the last fifty years since his assassination. His tone was changing even from his 1966 Mike Wallace interview where he said:
“I contend that the cry of "black power" is, at bottom, a reaction to the reluctance of white power to make the kind of changes necessary to make justice a reality for the Negro. I think that we've got to see that a riot is the language of the unheard.”

Dr King was heavily involved in protests. He did everything he could to keep his protests non-violent, but he faced extreme violence from the ~slave patrols~ white racist cops of the time. His son is on Twitter…and is being MLKsplained to by white people who consistently misunderstand what MLK said and meant.
https://twitter.com/OfficialMLK3/status/1266040838628560898 (follow the thread)
MLK’s position initially was very much the same as Michele Obama’s “When they go low, we go high”. But he never said that people should just _give in_ to the violence of the state, and so it’s pretty clear that he would not have completely condemned the protests or even the riots.
(In other words, there’s multiple MLKs, and most people—especially white people—remember the sanitized “I have a Dream” MLK that is taught to us as history. That MLK is _not_ the MLK that existed at the time of his assassination.)

A little further down:
"Homicides in Baltimore are heavily concentrated within a small number of high-poverty neighborhoods."
So, my prima facie impression from these data points is the stand down has not benefitted the poor.
It doesn't matter that it theoretically all happen in the browser. You can serve different versions to different IPs etc. Every heuristic in me would be screaming don't use that if I would have a need for such tool.
In either case, you're massively misrepresenting the "stand down" order, which was not a policy of indefinite disengagement, but rather a specific instruction given in the scope of the 2015 protests in an attempt to avoid further escalation. Whether or not the order was successful in that sense is a matter for separate discussion, but to claim it's a permanent thing, the way you are doing, is simply false to fact - which is probably why you still haven't sourced that claim.
While we're on the topic of BPD actions during the 2015 protests, have you heard about the cop who used the opportunity to loot drugs from a pharmacy and later sell them on to street dealers? [1] I suspect not; for all your apparent interest in the doings of the Baltimore PD, you seem surprisingly ill informed. That's far from all the Gun Trace Task Force got up to, either [2], nor were they alone in their corruption. These are things you need to know about, if you want to talk about policing in my town and expect to be worth taking seriously. But here you are, needing to be told about them. I wonder why that is.

I hope this doesn’t get me labeled as “white” or “moderate” (I am neither).
So what if a jury finds them innocent, which is highly likely? What do you mean "1992 will look like a joke"?
The article also, despite a clear editorial slant, can't quite avoid hinting at the kind of solution that actually does need to happen: not for police officers to simply abrogate the responsibility they accepted with their oaths when the public makes clear their conduct has been unacceptable, but for police officers to improve their conduct, and discharge the responsibility they took on, to actually protect and serve.
I grant that that lies outside the false dichotomy you choose to draw, between police doing nothing and police continuing in the massive abuse of power status quo ante. But, after all, it is a false dichotomy. You can do better.
I hope you can do better, anyway. For one thing, you promoted the deputy police commissioner, which I'm sure he appreciates, and spun the world clear around on its axis so he got mugged in the daytime, when he didn't, instead of at night, when he did.

These are very strange errors of fact to go on making with, it seems like, every single claim you've introduced so far. Wherever you're getting your information from, you might consider finding sources that do a better job of sticking to facts, because whatever you've been using up to now seems not much good at anything beyond leading you into error.
Actually, a lot more whites are killed by cops than blacks. And before you say that's because there are more white people than black people, blacks represent only 13% of the population but commit 52% of the crime. So, you are less likely to get killed committing a crime as a black person than as a white person.
https://www.statista.com/statistics/585152/people-shot-to-de... https://www.channel4.com/news/factcheck/factcheck-black-amer...
In this case its possible that the site encodes the data back in to the image but that seems unlikely.
You've made a number of unfounded leaps on top of that: That "Black people commit 52% of crime." This is wrong in several ways. You're assuming that conviction rates accurately represent rates of crimes, and also that "all crime" has the same statistics as homicide. But instead, we see that black people are convicted of only 27% of overall crime. That's including the fact that certain categories are known to be racially disparate in conviction and sentencing - e.g. white & black people use marijuana at approximately equal rates, yet black people are nearly 4 times as likely to be arrested for it. That the people killed by cops were all committing a crime at the time. I don't have statistics on hand for this, but a well-known counterexample is Tamir Rice.
A better example is Protonmail, a secure email service. It has a nice web client and there is an 3rd party desktop/electron version of the same size called Electronmail. While both essentially run identical code, the electron version is more secure because even Protonmail insert a backdoor for a single or # of users. They would have to at least publish the backdoor in the vanilla code at which point, the maintainers of Electronmail will probably raise the alarm.

Yes, deliberately preventing anyone from providing care or defense for a person who's being murdered makes you an accomplice to the murder.
>If your city charged these cops justly then nobody would be burning it down
Doubtful. Here's a video of East 4th street in downtown Cleveland being destroyed by pillagers last night: https://www.news5cleveland.com/news/local-news/cleveland-met...
There's over a thousand service industry workers who've already been out of work for months due to the pandemic that the businesses on this street support. Many of them have struggled to get enough financing to even reopen, some have had to permanently close. Many (possibly most) of these businesses are destroyed and can not afford to rebuild. Who should the city of Cleveland have charged justly to prevent this? How many more innocent and unrelated people's livelihoods need to be burned down and how many more times (this has happened before, more than once)? There seem to be a lot of accomplices in the video.
The only way an attack vector is possible here is if you think GitHub themselves would maliciously inject an altered version of the code in the repo, and even then you'd be able to see the code and network requests in your developer tools.
Yup.
And I personally think that a lot of the violence isn't the average protesters who care about police accountability, but people who are just using protests as an excuse to wreak havoc with less chance of being singled out for arrest.
Yes, that's right. See the connection between crime and cops killing civilians?
> But instead, we see that black people are convicted of only 27% of overall crime.
Where do you see this? I can't find this anywhere.
> That's including the fact that certain categories are known to be racially disparate in conviction and sentencing - e.g. white & black people use marijuana at approximately equal rates, yet black people are nearly 4 times as likely to be arrested for it.
That by itself doesn't show anything. It depends on how and where marijuana was used. Smoking a blunt and driving around the neighborhood with the top down is going to picked up a lot more than someone sitting in their home smoking. You need to show situations that are the same which have more blacks being arrested than whites.
> That the people killed by cops were all committing a crime at the time. I don't have statistics on hand for this, but a well-known counterexample is Tamir Rice.
Yea, I'm sure you don't... that subset has to be so minor it has to be insignificant. Oh, an anecdotal incident where a 12 year old boy carried a replica of a pistol and aimed it at an cop, who didn't know it wasn't real. I don't see how your example justifies this as a big problem.

Just distribute the code for local execution? Sure, it's less accessable for the target audience, but it is more transparent.
But what else is new? Most users are willing to sacrifice privacy and security for convenience. That's how we got into this whole mess.
If they don't get convicted, will you be terrorizing only the jury, or do you plan on victimizing other innocent people too?
I sure hope you don't, but if you do get your wish please remember to have everyone print and sign their names on the petition/ransom note/demand letter. When choosing targets for arson just be aware it will take longer to comply if you burn down the courthouse(s).

Don't tell people what not to do. Figure out why they're doing it, and provide what they actually want while still achieving the goals (here: security).

As for the journalist - in a riot situation, people are often detained temporarily as police are clearing areas. Once a riot hits, the police are within their rights to clear out areas. While the legality of temporary detainment varies, you should consider why police are all carrying handfulls of plastic ties ... to detain people.
In some cases, the police were shooting rubber bullets in the direction of protesters wherein there were reporters - there's nothing wrong here.
In some cases, the police were shooting pellets directly at reporters, I don't think this is fair or right, but it still doesn't abnegate the need of cops to be there and to clear people - also - we never know the full details. Maybe the police had warned the crew to leave several times before.
Once things turn into a riot, it's going to be a little bit of a fight, there's no other way about it. If this were 50 years ago there would have been batons cracking heads, thankfully we don't have that. We have have now is actually fairly mundane.
Also, the regular protestors, during the day, are allowed to do as they please generally speaking which is fine.
I mean, I get what you mean, but this is literally what's already happening. It's distributed via HTTP, and executed in your browser. You can save it (Ctrl-S, still a thing browsers do), and -- since it's distributed in source form -- easily inspect it, or reopen it later, in a different browser on a different computer. A zip file of the same thing is available on the repo (it's a zip of the repo).
If you don't trust that it won't access the web, disable your internet while running it or some such, as with other code you don't trust. If you don't trust it to mess with your files, well, you're in luck because modern browsers are probably the best audited sandbox out there.
I say I get what you mean, because most people won't do any of it. Instead of saving the page and running what they trust or have verified to be a safe snapshot of the page, they'll reopen the hosted version, trusting that it's still safe, even though the page may have been replaced with one that does upload their files.
Are we in agreement that this was documented as happening, and the other cops present were accomplices in the murder of George Floyd? If so, why do you think they aren't being charged?
>Who should the city of Cleveland have charged justly to prevent this?
I assumed GP meant Minneapolis, which I feel is reasonable given the context. But okay, random US city accepted. Let's see if your city has a history of letting cops get away with killing innocent black people... oh yeah, one of your cops killed a 12 year old kid who was playing airsoft in the park and was subsequently hired by another police department in the same state without facing any charges.[0] So maybe charging Tim Loehmann would have helped make your city less sensitive to this pattern being repeated elsewhere in the country.
I don't think violence against businesses is helpful, but I do think violence against the government is helpful; it seemed to get a cop charged. They need to stop this pattern of violence ASAP, and they need to face time for crimes committed.
I assume the GP means the civil unrest that will happen if there is an acquittal would be much worse than the LA riots.

Users are disclosing to the website what they hope has not been discovered by someone else -- e.g., usernames and email addresses, or in this case photos, they hoped to keep private. Unfortunately, the website is "someone else".
You're legitimising mass violence, and then condemning those trying to stop it, who in some instances might step too far.
A police Officer and others have been killed, the riots are spreading and it's obviously a problem.
There are riots in major cities - fairly aggressive violence and widespread property destruction.
This absolutely necessitates a physical response by police.
There is no way around that.
To expect absolutely perfectly defined behaviour in a perfect legal sense from some people in a situation, and then to completely ignore the violence by others, which is the cause of underlying problem, is some really difficult logic. Obviously the bar is higher one side, and accordingly behaviour is mostly better.
There are thousands of people looting and rioting and destroying things.
The police are responding fairly proportionately.
The 'daily protests' it seems are going fairly well, peacefully, but the evening situations are basically just riots.
As for your 'examples' ...
If police are slashing tires and tazing people arbitrarily there's no excuse for that, they should be punished.
But a woman was 'shoved'? Why does anyone think we have the right to physically or verbally assault government workers or anyone else, and for there not to be some kind of reaction, and in some cases overreaction, that is frankly, somewhere in the range of proportional, and not a big deal. We didn't see exactly what happened, but there is clearly a physical confrontation going on, while I wouldn't support at all an officer just arbitrarily shoving someone, there's a lot on that table to discuss.
The 'press officer arrested'. This again, I don't think is a story. In a riot, if police are asking people to move somewhere, and they don't, it's very reasonable for people to get detained for a few minutes as they are moved out of the way. In fact, that's a pretty 'civil' example of unrest and the management of it. I don't know all the details actually, but as police are clearing a riot scene of mass violence, having to temporarily detain some people seems reasonable.
There's also the issue of a 'freelance journalist' hit with pellets or something along those lines. A lot of people were hit with pellets - just because someone is carrying a camera, does not give them some kind of legal immunity. Again, we're missing details - if she was standing out of the way, where she was clearly not participating and the cops just 'shot her way' for no reason, well, that's bad. On the other hand, if she's thick into the riot and pellets came her way, well then I think it seems rational, if tragic, that this would be the outcome.
If those thing were happening without any riots or legitimate need to be respond, then it would be really bad, but in the context of literally trying to suppress riots, that's not a 'police state' - that's literally just police dispersing a riot and getting people to go home or indoors.
Already a Police Officer has been killed, one protestor has been killed purposefully, and another killed while accidentally dragged behind a vehicle? And there's probably a billion or so in property damage and lives ruined? This is serious stuff, far beyond the legit protests we're seeing mostly during the daytime that nobody has a problem with.
All of the videos and incidents I linked showed 100% from multiple angles that the police were the ones instigating the issue. They shoved a woman out of the way because she was just standing there and sent her to the ER. Journalists were blinded because they were simply doing their job and the police decided to take potshots. You're arguing about 'legal immunity' when we're talking about cops blatantly breaking the law and abusing their privilege as police officers to get away with it. And the reason why this entire incident occurred was because of police murdering someone so obviously that people couldn't look the other way. Maybe you should start by blaming them for instigating this whole mess.

(Sorry for commenting on you twice in this thread--I promise I'm not trying to follow you around. I'm all about dissecting the quality of a system or toolchain! A false sense of security can be more dangerous than naïveté! Caution and skepticism are often our only protection! Trusting random websites is Not a Good Idea! But, security tools average people can't use are also meaningless here.)
The reporter shot in the eye and the reporter temporarily detained were literally at riots in Minn. Being at a riot when the police have lawfully asked you to leave is 'instigating'. Literally requiring the police to come and use force to move them, and 'the police are the instigators'? This defies reason.
And the 'shoved' woman in the video walked right up to the police officer and was clearly saying something - I don't think it justifies the response but she was literally instigating a confrontation.
" Maybe you should start by blaming them for instigating this whole mess."
I don't 'blame police' because one of them did something egregious, I blame that officer, just as I don't blame 'Americans' or reasonable 'protestors', for looting, murdering, destroying things - I blame the people doing it.
but, in baltimore that just led to lax police, more crime, and more homicides
i believe the same will happen with these riots. police will withdraw from blac neighborhoods, and the criminal element will have free reign. that is a bad outcome, and more innocent people will suffer than will benefit
we are trying to make life better for innocent black people, but being scared of the neighborhood gang bangers is not a step up from being scared of the police
and this will not bring justice for the victims, police may throw some sacrifices, but they otherwise will just be less caring about black neighborhoods and police mistreatment of black people, and the gulf will widen

Your question is on target--one I've wondered myself--but I've come to the conclusion that it isn't for people who already have the sense not to put their passwords in random forms on the internet.
I can only assume it has 2 main uses:
1. Poke (some) holes in the bubbles of people with dated password hygiene practices (and a poor sense of how good other humans are at helping attackers reduce the possibility space) by giving them a playground to make new passwords against for a while.
For example, I decided to enter "silverfish3" in the form because I know more than one person who still uses <noun><number> passwords that are multiple characters shorter than this one. It's still turned up in the database 40 times. "dichotomy14" hasn't been pwned yet, but "dichotomy7" has already been pwned 5 times.
You don't have to use a real password of your own to discover that your schema is well explored.
2. I can only hope HIBP password search has scared a few thousand of the kind of person naive enough to fill in the form with a real password straight.
Edit: to be clear I meant this as a commentary on the technology, not the people making the mistakes
You mention the pandemic. Somehow, our Congress has passed (in nearly unanimous fashion) five giant "bailout" laws supposedly in response to the health crisis, which have given trillions of dollars to powerful interests and pennies to normal citizens and none of the blessed laws have done a single blessed thing to provide health care to control the blessed pandemic! Meanwhile, comparable (though mostly poorer) nations have provided state-supported healthcare to all citizens, for decades. Are we sure the protests are only about racist cops? Besides, when they burn down the Nike store they aren't destroying too many American jobs.
I did not suggest distributing an executable. I suggested distributing code, so that the user could audit it before execution.
I did not realize this tool executed all of its logic in the client when I made that post. It is rare to find websites with plainly-written, unobfuscated, uncompressed, vanilla Javascript that don't rely on any server-side processing.
HIBP offers you a way to validate a password has been compromised, HIBP does not offer you a way to determine it has not been compromised or is otherwise suitable for use. It’s a service for excluding compromised passwords from use.
It sends a GET request for "https://api.pwnedpasswords.com/range/89F5D"
and gets back 548 rows of the form:
001F74CD3E241B7820C996DA4FB3BDF9FE7:2
...
54C7FB299EC06A0B979C5DE14F1AE61F653:40
...
FFE6FF5698CEC527CD18269D1B7697C8743:1
Note that middle example row with ":40" at the end? Prepend "89F5D" from that GET request the javascript generated to that row's contents "54C7FB299EC06A0B979C5DE14F1AE61F653"
Now compare that to what you get when you run this (This is a macOS specific invocation of the command, but something very similar should work pretty much anywhere):
$ echo -n "silverfish3" | openssl sha1
(stdin)= 89f5d54c7fb299ec06a0b979c5de14f1ae61f653
You might (perhaps rightly) not trust Troy's site to not switch out the javascript underneath you, but you _can_ trust the API, and could always run:
curl https://api.pwnedpasswords.com/range/89f5d
Or, if you're testing that "dichotomy7" password:
echo -n "dichotomy7" | openssl sha1
(to get (stdin)= 772be5bd14dc626ec7fa952b51ae28c482e92d39)
then:
curl -s https://api.pwnedpasswords.com/range/772be | grep -i '5bd14dc626ec7fa952b51ae28c482e92d39'
will show you your result of that dichotomy7 password having been seen 5 times.
You've only revealed the first 5 characters of the 40 character sha hash to the server. That might have been one of the ~500 passwords with that same hash, or any of the rest of the 150 bit space of other strings that hash to that prefix that are not part of their database.
I would be perfectly happy running echo -n "{{a real valuable password of mine}}" | openssl sha1 locally and then feeding the first 5 characters of that into "random apis on the internet".
On a somewhat related note, I wonder if the thousands of people being recorded committing various crimes in the US right now realize that their faces are almost certainly being compiled in various government and private databases, to be matched via facial recognition for the rest of their lives. Yeah, not necessarily a good thing, but am I wrong?
But it doesn't matter what you or I can prove the site does or doesn't do with our passwords; my dad or aunt shouldn't type their passwords into random forms on the internet. Whether it tells them it's using k-anonymization or not.
You still wouldn't pop your dev tools open but then type your real password into a random form on the internet before you'd kicked the API-tires with some fakes.
Anyone who isn't prepared to kick the tires and hasn't established a trust relationship has no business doing it.
I believe you're having problems thinking clearly. Here, in a public forum, you threaten
"A billion dollars of property damage and the targeted destruction of businesses operated by Korean immigrants..."
which is little more than a megalomanic wish. Shouldn't you be taking some medication or, at the least, seeing a psychologist instead of wasting our time here?
I think the only way you would ever change your mind is if you went to one of these protests just to observe peacefully and respectfully, and then get caught up in a sweep. Experiential learning is powerful stuff.
Please bear in mind that this topic is not about denying rightful enforcement of law, it's the exact opposite: ensuring enforcement of the law is just and in the interests of all.
I think there could be a pretty compelling 1st degree case there, since the officer had Floyd's neck under his knee for so long. He could have stopped the assault at any point.

Isn't this way below the HN discourse bar?
I think murder requires some threshold of intent deliberation and I'm not very familiar with the details in this incident just yet... but on it's face it's doubtful the officer intended to kill George Floyd and choose a slow, public asphyxiation concealed by the unreasonable/illegal restraint while having him legally detained as a forgery suspect. That, of course, doesn't absolve him of being directly responsibility for this man's death. They are not being charged (yet) because: it's only been a few days, only a very small percentage of crime commission results in charges, having charges at this point in time would have required the suspects to issue charges against themselves/each other and if one of them had that much integrity, George would probably not be dead in the first place, convicting the officer of murder may be difficult, so accessory or accomplice charges will require careful deliberation, information still being gathered, among other reasons.
FWIW, the people filming and/or spectating as George Floyd was killed bare some moral/ethical responsibly for their lack of (or cowardly?) effort to physically interject, although I'm aware many will not agree with me here.
Concerning Tamir Rice, a person called in to report 'a man in a dark hoodie at the park playground, waiving a handgun around pointing it at kids, they think it might just be a realistic looking toy gun' or similar to 911. The dispatcher called a unit to respond but did not include 'think it may be a toy gun' portion of the callers request for a police response. The officer spotted Tamir, standing alone, from 100 yards or more across the open field in the park. The one driving speeded across the field toward Tamir and pulled up close with officer Tim Loehmann in the passenger side, putting him directly in front of Tamir. Allegedly Tamir brandished/pointed/pulled out the gun and officer Loehmann fired in response and fatality wounded/killed the young boy. It was tragic and there were dangerous mistakes made by multiple people but charging the officer who gunned Tamir down with murder would have almost surely resulted in acquittal. Mr. Loehmann then fraudulently concealed his background and got hired as a rookie officer in a small town across the state, then was subsequently fired upon discovery of his past.
The amount of violence, fear, division and destruction I have witnessed in the name of 'Justice for Tamir Rice' is also tragic. Protesters blocking roadways, terrorizing restaurant patrons and vandalizing or destroying uninvolved businesses every time someone else with a similar color skin dies unjustly does not help prevent the CPD from shooting innocence black children.
It seems that 'rules of engagement' between police and civilians have been eroded over time while executive authority has been expanded. This current state of anarchy can be greatly improved with discussion, consensus, enforcement, and public awareness of these rules. Until then some police will continue to act like mobsters and most will accept, take advantage of or enable some level of legal privilege because of their position. Body cams show us that unequal, crony, illegal, racist, and biased enforcement is widespread. Police in America conduct silent home invasions for non violent drug charges, shoot innocent people and pets without consequence (sometimes at a mistaken address), routinely profile otherwise cooperative non violent people as a threat in order to unlawfully discriminate. They point guns at these threatening people with impunity and treat them as hostile while being so threatened by guns that they can justify driving up to a 12 year old in a park with a fake plastic gun and open firing, no words exchanged. This is an area where legal reform and awareness severely needed.
Burning down Wendy's may have influenced a reactionary, politically motivated, premature legal filing. It will probably compound the hardship of those peoples and family's whose jobs and paychecks were destroyed. It will surely hurt a struggling economy and further stress the community by destroying a busy, low-cost prepared food resource and it will deprive the Dave Thomas Foundation of all future donations during a time of intense need.
I have only ever observed PPM comments right at the start of the file, so you could open it in a text editor and remove the comments from the start. Maybe check the very end of the file as well.

Could you train a model with your own face as a start, and then run your photos through an existing consumer face-swap app? Or perhaps use a celebrities likeness? I wonder how much the visual 'likeness' of a stranger is worth.
I should add: In all of the streams and pictures I've seen, all (most?) the looters or violent people were wearing masks, ensuring their anonymity. If anybody's being protected by measures like this, it's your average peaceful protestor.

There should be a test suite for image editing applications which will validate the different ways of editing a file to see which ones work as expected and which do not. I’m thinking something similar to web standards test for browsers. Does something like this already exist?
I don't think the man who killed Tamir Rice understood that he was shooting somebody holding an airsoft gun, but if the killer wasn't a cop then I seriously doubt that they would have decided his actions in that situation were reasonable as self defence -- they probably wouldn't clear me of all wrongdoing if I claimed that a 12 year old kid pointed an airsoft gun at me before I killed him. There's a double standard. Despite the victim being a 12 year old, I can see how this is less egregious than what I consider to be the clearly intentional killing of a known-to-be-helpless George Floyd -- I brought it up as an incident in your specific community where this pattern of violence bubbled up so dramatically that it received nation wide news coverage. I think you misunderstood some facts around the hiring and firing of the cop. He lied on paperwork at the original (Cleveland) police department, which is the technical reason he was fired -- it came up during a review of him following the shooting. The other (Bellaire) police department knew what they were buying. A quote from the link in my last reply:
>“He was cleared of any and all wrongdoing,” the Bellaire police chief, Richard Flanagan, told The Times Leader of Martins Ferry, Ohio, adding that it was unfair to “crucify” the officer. “It’s over and done with.”
I could see there being a causal link between how your city handled this incident (as well as others like it) and how much violence you're seeing now, a few years later, when everybody is focused on this other prominent example of the pattern.
How does this work?
2 cases:
1. I know password P is compromised. I check it in HIBP. If compromised, great, but I already know that. If not, well, too bad. I still can't use it because I know it's compromised. - decision doesn't depend on the result of HIBP.
2. I don't know if P is compromised. I check it in HIBP. If compromised, I don't use P. If not, I don't use P because I already put P in a text box connected to the internet. - decision doesn't depend on the result of HIBP.
Don't get me wrong, I'm well aware of the value of HIBP. I'm just arguing about this particular use case.
Odd, my dogs are barking
Just like MLK is regarded as "peaceful" when in fact he and others spoke quite a bit about the fact that there was never any response from white people unless property was attacked.
The problem in this case is that its institutionally racist towards, and extrajudicially assassinates, black people with impunity.
We must be more precise because otherwise it allows _this_ to happen.
If you remove high frequency details, you in effect remove distinguishing features. That it is possible to create an absolutely convincing high-detail image that if blurred, gives the same "original" blurred image doesn't mean you have the correct deblurred image.
With not too fancy methods, I'm pretty sure you can make a blurred image identify as any multiple people.
I don't think this is a controversial statement either. In any case, this is a tangential discussion, since blurring to hide identities is a flawed method to begin with. With video recording, tracking, grouped individuals, etc, I'm sure reconstruction with good databases of likely subjects can have some surprising accuracy. So, better to avoid it altogether.
That said, one image, sufficiently blurred with a proper low-pass filter (i.e not a softer gaussian type, but one that just removes frequency ranges altogether), will absolutely not contain information to identify someone. The information literally isn't there. A large number of people are an equally good match, and then no one is. But, since combined with other methods I mentioned, it's a bad idea, then, yes, it's a bad idea.
Do you know if a waiver is needed in this case? My understanding is that I can walk down a sidewalk, around Disneyland, around a resort, and film anyone / anything in plain sight. (I don't do that, by the way...) In other words, assuming you're not climbing over railings etc., if you can see it with your eyes, you can film it or photograph it.
Wonder if anyone here (plenty of legal eagles I'm sure) can confirm this or correct this. We don't need to get bogged down in corner cases & rare exceptions... for example, I think I heard that in some states, if the police ask (demand?) that you stop recording, you have to, otherwise you're in violation of the law... but even as I type that, as an American, it just sounds wrong... but I don't know.
This particular site is with respect to Canada, but I'm pretty sure the same basic idea applies everywhere:
"When publishing photos for commercial purposes: You need the permission of every identifiable model in the photo, even if the photo was taken in a public space. For example, if a photo has 10 identifiable models in the photo, you would require a model release for each of them."
https://www.lawdepot.ca/law-library/faq/model-and-entertainm...
I'd also like to know how mosaicing is reversible, since it demonstrably reduces the total available amount of information from e.g. 20x20 = 400 RGB values to a single RGB value. This is not sufficient for text where you can start brute-forcing individual options because the search space is small and inputs can be reconstructed precisely, but I'd like to see an explanation why you think this is reversible for photos (even without noise added). I'd also like to know how you want to remove random noise applied to each mosaic block.
The mosaicing is supposed to be the security step here. The blur is optional eye candy not expected to remove further information.
In particular, if you claim that a face mosaiced with a large "pixel" size (e.g. so that the typical face is 5x5 "mosaic blocks" big), you're effectively claiming that you can perform facial recognition based on noisy 5x5 pixel images.
Same for the .heic files on my iPhone, too.
it doesn't matter though. as I've explained, it's far easier to come up with flawed schemes than prove them insecure. just because I can't explain why your specific scheme is insecure doesn't mean it stands a chance against real cryptographers.
Hence my suggestion to reduce a face to something like 5x5 blocks.
While I'm familiar with the crypto design problem, this is not a crypto algorithm. Sure, it can't be ruled out that someone in the future will find a way to do it, but the state of the art says that 5x5 pixels are not anywhere near enough to run face recognition.
And a solution that may be broken in the future is often much better than a solution that people don't use because it doesn't meet their needs, which in this case is not having fugly black boxes in their picture.
Maybe check real sites instead of your usual racist ones? Google is a good start. Here's the first link! https://www.sentencingproject.org/publications/un-report-on-...
