I was thinking at the very least to get a citizen right where you can request to have any encounter with the police recorded.
‘Officer I request my right to have this encounter recorded’.
1. Body cams mandatory for all police inside & outside of the station, and they stay on 100% of the time and batteries should last the whole shift. No ifs/buts/maybes. If the need arises, bathroom breaks can be edited out after the fact.
2. National ID card, in all states and mandatory for everyone over 13/16. Put all biometric, facial and possibly DNA data on file, encrypted and only available for searches. Be creative.
3. Remove the need to arrest people for any non-violent crimes. People are positively ID'd via some tech (insert something wild here if you want). Cop files a report, includes evidence of positive ID, person needs to appear in court as they will be notified by SMS/Email/letter/lawyer-visit because that stuff should all be on-file and up to date. Send them warnings if they don't appear in court, meanwhile block their access to everything like cell-phones, bank accounts, etc. Start pro-actively messaging their family, or them, and let them know about the additional time/fines they are racking up by missing court dates. 3.a) Assume they're guilty if they don't show up for court and don't have a valid reason.
4. Disallow police from forcibly cuffing people for arrest. Procedure should be to throw two pairs of cuffs at the person while they're being pointed at with gun/taser, and they have to put it on themselves. Procedure allows for x minutes of that, then by default they have to taze this individual into submission and just arrest them. Once they're cuffed, just carry them in a car/van, or wait for support.
5. Punishment for disobeying orders by a policeman to do the above.
6. Very strict guidelines and sets of laws being broken that justify physical arrest. The default should be to just tag the person and tell them to appear in court. If it's a grey-area, just block their cellphone, bank-accounts, cards, etc.
7. Track all cell-phone locations, strongly-linked and verified to individual identities, and store permanently. Store it securely and allow court-orders to open for case investigations. Allow anonymized access to information-based researches that are told to investigate crimes. This one alone could solve so many crimes in my view that I am saddened to no end that people prevent it from happening safely at the recurring expense of innocent lives.
One could go on and on. But guaranteed the above sets of actions/laws are very unpalatable for the majority of people, and it would cause "human rights lawyers" to salivate at the potential for litigation and for "human rights activists" to salivate in protestual anger.
People stop it from happening (to some degree and at great cost) because this would hurt far more than it would help. Imagine if the police could do this now. They would use it to drag everyone who had been in the vicinity of the protests out of their homes and lock them up (at best). "Secure" and "court orders" would never hold up in practice, but "permanent" certainly would. Plus, all criminals would need to do to avoid it is not bring cell phones to crimes, or bring someone else's. Unless you want to mandate carrying government tracking beacons at all times? I'm no libertarian, but this is one of the worst proposals for fixing police brutality I've ever seen.
