The police don't care what the taxpayers have to shell out, it just means sitting through some angry lectures but basically they are no worse. I think compensation for victims of police misconduct should come out of police pensions.
Lots of police officers are reasonable people trying to do a difficult job with integrity. but the job also attracts a lot of bad people who exploit their authority abuse or kill people, and there are types of politician and voter who support that kind of behavior and choose to advance it.
