I'm all for that. But systemically we tend to oppose that too. You do that long enough, eventually the ones on the bottom start pulling down statues. But the problem is both. We have victimless laws, and we have law enforcement departments with histories of covering for their own people when they break the law, or exploiting loopholes to railroad people.

How do you deal with police forces ignoring policy and performing as they deem fit all while protecting themselves?

Burn qualified immunity to the ground and salt the earth. This would be the simplest way to keep police accountable for their behavior. It would also imply a massive change in how policing is done (demilitarization), so that's two big wins.

We can lay a lot of the rotten police problem in the USA, and the world, at the fact that the accountability just isn't there.

I always thought only hiring police officers from the area being policed was a good start.

I don't mean that if you hire someone they have to move into the district. I mean that your pool of hires is the people who have already lived in the district for a particular amount of time (years).

The locals know what laws not to enforce and how to gain the trust of the community.
