This triggers riots and protests, which require the police to work overtime.
They get paid for causing all these problems, and well paid. Their overtime costs must be tremendous. And who ends up paying? We do.
We should claw back police overtime pay for any protests or riots that are caused by the police themselves. I think that's fair and equitable.
You have some outliers that are violent and the rest just does their job - keeping the city more safe.
Also don't assume all cases of police officer shooting a person are cases of police brutality - this is for court to prove.
That it does not seem to be happening unless there is video and public outcry suggest the issue is cultural and institutional, not just individual. The good cop is not reporting bad cop and is not testifying against him. Maybe the good cop would be retaliated against, maybe nothing would be done, and all of those are reasons why bad cops are empowered.
