> It’s intuitive and true that poor homes and neighborhoods are going to house more crime.

I challenge your assumption. To me it seems intuitive that crimes are committed at higher rates by the socioeconomically advantaged, because they can get away with it.

See for example that immigrants commit crimes at lower rates than the general population.

The last 40 years of austerity politics in the US have starved the beast [0] so greatly that the only remaining public infrastructure that functions as it's intended to is policing. For example, in the city of LA, 53% of the city's unrestricted general fund budget went to the LAPD.

For everything else, there are parallel infrastructures for the haves - private education, private healthcare, privatized transit, etc. It's something I've thought about a lot in the last few weeks.

On top of that, there is some research that suggests communities rate smaller police forces better than larger ones [1].

> To test this, Ostrom worked with the Indianapolis government and her students to measure the quality of policing. Surprisingly, against common assumptions, they found that the smaller the police force, the more positively residents evaluated the police services they got.

> "Increasing the size of [the police force] consistently had a negative impact on the level of output generated as well as on efficiency of service provision… smaller police departments … consistently outperformed their better trained and better financed larger neighbors.”

> But why did this happen? To explain this, Elinor Ostrom argued that in small communities with small police forces, citizens are more active in community safety. Officers in smaller police forces also have more knowledge of the local area & more trust from people.

Do you have any data to back up that claim, other than anecdotal "evidence"?

Here's some real data: https://www.bjs.gov/content/pub/pdf/rpa11.pdf

Across all races and Hispanic origin, American Indians and Alaska Natives (15%) and persons of two or more races (15%) had the highest rates of reporting crime or neighborhood disturbances to the police. No statistical difference was observed between the percentage of white (9%) and black (7%) persons reporting a crime or neighborhood disturbance to police in 2011.

Also, perhaps I'm reading it wrong, but Appendix Table 4 suggests that minorities are much more satisfied with police response than the average.

There is no austerity. Here is state-and-local spending as a percentage of GDP from 1970 to present: https://s3-us-west-2.amazonaws.com/courses-images-archive-re...

And here is GDP in 2010 dollars: https://data.worldbank.org/indicator/NY.GDP.PCAP.KD?location...

State and local governments went from spending 10% of $23,000 per person to 15% of $55,000 per person. Per-person state and local spending went up by a factor of 3.5, even after adjusted for inflation.

With respect to public infrastructure specifically, there has been no austerity. For example, here is a graph of NYC subway ridership from 1970 to 2014: https://i0.wp.com/plot.ly/~millerstephen/4.png?w=773&crop=0%.... Subway ridership is up 75% since 1980. The capital budget during the 1980s averaged $3.4 billion annually in 2020 dollars: https://wagner.nyu.edu/files/faculty/publications/rescue.pdf (fig. 5). The 2015-2019 capital program (5 years) averaged about $6.5 billion 2020 dollars. So a 90% increase in capital spending for a 75% increase in ridership. Punchline: MTA is so massively wasteful, that wasn't enough. The system deteriorated the whole time leading to catastrophic failure in the last few years.

The London transit system, by contrast, spends about $3.2 billion in capital expenditures to run a system that is very similar in terms of age, size, etc: http://content.tfl.gov.uk/tfl-budget-2019-20.pdf. Despite spending half as much money, London has been able to significantly grow the network while keeping maintenance current and maintaining on-time performance.

Honestly, invocations of "starve the beast" and "austerity" are nothing more than gaslighting. It's a cop-out for why our public services are so shitty, even though we spend vastly more on them than we used to spend.

The US actually spends a low amount of money on policing compared to the EU, where police kill fewer people. Further, the US also has a low number of police officers.

https://blog.skepticallibertarian.com/2019/01/09/charts-poli...?

https://en.wikipedia.org/wiki/List_of_countries_and_dependen...

The defund the police narrative isn’t based on any actual examination of US police spending, or general public spending. The key issues are instead police unions, lack of police training in the US, impunity for police abuses, etc

Cambridge NJ is often cited as a model of reform. But I am not sure they reduced spending. Instead they disbanded and reformed their police.

> The last 40 years of austerity politics in the US

Wikipedia[0] says that "[austerity] is a set of political-economic policies that aim to reduce government budget deficits through spending cuts, tax increases, or a combination of both." That strikes me as a correct definition of 'austerity'. But we've not had any spending cuts in real terms or in terms of GDP. Nor have we had tax increases for the past "40 years" -- sure, Presidents Bill Clinton and Barack Obama raised taxes, but Presidents Reagan, Bush, and Trump cut taxes.

Yes, reducing budget deficits has been a stated goal of most Presidents since 1980, but that's mostly been lip service. None bothered to actually try. President Clinton did manage to reduce the deficit, but not because he wanted or tried to, but because of the unexpected revenue growth caused by the unexpected economic growth caused by the unexpected IT revolution.

> For example, in the city of LA, 53% of the city's unrestricted general fund budget went to the LAPD.

What was that in 1980? Was there a step in this, say, around 1996? Did it go up in 1996 when Federal funding for 100,000 new police officers dried up? I.e., did President Bill Clinton's well-meaning 100,000 police officer initiative have unintended consequences?

> On top of that, there is some research that suggests communities rate smaller police forces better than larger ones [1].

I don't doubt this! We saw in Ferguson, MO, that the police was giving out an inordinate number of traffic fines every year! It's almost... exactly as if... they were paying themselves with that -- a terrible corruption. As I recall the number of citizens in NYC who have fines in arrears is staggering. Police department funding via fines is a form of corruption, and strongly indicative of police departments being too large.

And the invention of civil asset forfeiture (in the 80s, IIRC), and the rise in its use (in the mid-90s, IIRC), also seems like police (and prosecutors) paying themselves with poor people's assets. And it is invariably the poor who have been hardest hit by civil asset forfeiture.

The police have to be sized appropriately to:

  - investigate and close most cases
  - support investigations appropriately
  - provide a minimum of neighborhood police
    presence to deter crime and build a rapport
    with the community
Also, police need to be sized appropriately for dealing with civil disturbances, though here calling on neighboring districts when needed can help reduce the size of police force needed.

The police departments of most large U.S. cities are almost certainly oversized at present. One of the first steps in remediating some of iniquities of our system should be to end police department funding via fines and civil asset forfeiture (by simply ending civil asset forfeiture -- as clearly unconstitutional a practice as any). In some States fine revenue is shared with the State, but perhaps the amounts of the fines should go down and the percentage that goes to the issuing jurisdiction should go down significantly. At the very least the parameters of traffic violation fining need fine-tuning. Once the police can only be funded by general revenue of the local town/city, and the towns/cities cannot fund themselves with fines / civil asset forfeitures, we'll see a proper reconsideration of police funding.

I.e., the police need to be not so much defunded as right-funded, and today that would generally mean spending less on police. I'm not sure that in 1993 it was the case that the police needed to be funded more, though I'd be happy to see evidence to the contrary. Crime rates did go down significantly in the 90s, but those extra ~80,000 new police officers are not the only cause of that, and probably not even a major cause at all. The main cause of the fall in crime rates in the 90s seems to have been demography.

PredPol is a precrime system written by a mathematician (an assistant professor of math and CS) which recommends where police officers ought to patrol. [2] PredPol was deployed in Santa Cruz and Los Angeles, CA.

Likely a large portion of what they saw was a product of racial and political demographics. Whites are a larger percent of rural populations than cities. [0] White people on average rate police much better than non-whites. [1] Of course whites may rate police better because they live in rural areas, but the gap in satisfaction between whites and blacks is too great to be accounted for by more whites living in rural areas. Also rural people are more likely to be conservative and conservative people rate police much higher. Rural officers are in less danger in rural areas, so they may not need to be as alert and forceful because they know their lives are not in danger as much.

A mix of inefficiency and corruption.

Transit capital projects in the USA, for instance, are typically delayed for many years by lawsuits over environment laws, etc. For instance, near the nation’s capital: https://bethesdamagazine.com/bethesda-beat/transportation/pu...

> “PLTC and its member companies should not be required to finance the hundreds of millions of dollars in added costs for issues that are out of its control, not of its making …,” Risley wrote.

> More than 970 days of project work were affected by delays caused by the MTA, he wrote, which included third-party lawsuits, delayed right-of-way acquisition, and changes to regulations and third-party agreements after the project started.

And on the other hand, there’s straight up corruption and fraud. https://www.nytimes.com/2020/02/03/nyregion/cuomo-andy-byfor...

> “They are working here?” Mr. Cuomo asked. Not a soul was in sight. “Yes, sir,” the man replied, nodding vigorously. “They must be very short people,” Mr. Cuomo said. “Or invisible.” About 130 people were being paid to work until 11 p.m., though their day had clearly ended well before that.

Can you give an example of a country that does what you recommend? If you can’t, what evidence do you have that it is the solution?

I’m not American. My criticism above is that the movement appears to have developed a policy idea that is not used in any country with a successful policing track record.

As for your claim that individual districts can’t take action....why? Cambden did. They’re hardly perfect, but it’s an improvement. They’re a local area.

And this story shows that when they did try cutting funding, before the reforms and it didn’t solve the problem. Only a concerted reform effort did.

https://www.nbcnews.com/news/us-news/new-jersey-city-disband...

Comment above was heavily downvoted, but no one has provided a meaningful reply to the stats. The numbers are clear. Compared to places with better policing, the US has a smaller number of officers per capita, and spends less.

The US does spend much more on prisons however, which is surely a mistake. To your point on shifting focus away from punishment this is one of the first places I would look to cut money: prisons.

In the UK, police killed only 3 people in 2019. There has been surprisingly little inquiry as to how they do it. I get that US police are bad, and so spending less money to get less of them might be an improvement. But to actually solve the problem it seems that changing the police is the better answer. And this will necessarily be local because most of the important stuff in the US is local.

Just because the spend per rider increased over that time doesn't mean the system is getting what it needs though. A newer system will usually function better than a starved system years later naturally because of deferred maintenance and other aging infrastructure ailments even if the per rider numbers have increased. Comparing it just on the per rider spend assumes that the earlier number is enough.

African Americans are killed by police at the same or lesser rates than other races. However, they are killed at much higher absolute rates because they commit a significantly greater amount of crime. It doesn't take a PHD in mathematics to figure this out.

Here is just one data source from NYC: http://www.nyc.gov/html/nypd/downloads/pdf/analysis_and_plan...

Subjects firing on Police: 79% Black

Subjects killed by Police gunfire: 69% Black

If you want to tackle Black crime, start with decriminalising drugs, and then getting Black fathers back into marriage and raising their children.

Destroy the idea that being law-abiding, studying hard, and being regularly employed is 'acting white'. Scale back welfare to make all these things more attractive, and restrict immigration to direct more job opportunities to African Americans instead of Latin American and Indian migrants.
