I'm not sure what point you're trying to make. While many of the police actions are inexcusable, trying to have a society without an active group of people enforcing law and order doesn't work well. Just look at Baltimore for the downsides of police inaction.

Baltimore police are not exactly inactive, they are more like an organized gang (https://www.google.com/amp/s/www.baltimoresun.com/maryland/b...).

Here's data on the drop in police-initiated policing following Freddie Grey's death - https://www.usatoday.com/story/news/nation/2018/07/12/baltim...

When people start policing the police force, don't they become....the police (by definition, not legality)? And therefore susceptible to becoming just like the "idiots/assholes" they were empowered to deal with.

Certainly an interesting recursion problem.

The solution to that is not having an "empowered" caste, and leaving it to a community to police themselves.

Everyone tends to get nervous about that though.

Something about witch hunts and lynching perhaps?

Both of these represent the same phenomenon as the modern police force, which is class oppression (in the first case anti-intellectual misogyny, in the second the same base racism underlying the current struggle). Communities can and will self-regulate, when let out from under the thumb of state-sanctioned violence.

What is “the community” supposed to do if there’s a murder or rape?

no, because they don't have authority to police civilians. there is no recursion here.

police force -> used to arrest dangerous criminals only

police wardens -> used to review, charge, change police policy, and arrest police officers who violate the law.

social officer -> used for all non-violent community enforcement. fines, ticketing, homelessness, mental health issues, etc. have no power to arrest anyone.
