I feel like the system works pretty well.
Cops have an impossible and dangerous job. They get a lot of leeway when it comes to use of force because they’re making split second decisions in extreme circumstances. They make mistakes like everyone else. When they’re deliberately abusive or misuse the public’s trust they should be held accountable.
Not really sure what cataloguing the bad apples accomplishes other than riling up the many Geeks who cheer on police brutality.
