- steals $200K from you - has their attack dog bite you you while your calmly sitting down and handcuffed - serve a warrant for someone they already have in custody by breaking down your door in plainclothes without announcing themselves and then shoot your girlfriend eight times.
(These are all real cases from this year, where the courts rules there was not grounds to sue because of qualified immunity)
Now, you can at least sue them for such actions. I suspect the damages will be paid for by an insurance policy taxpayers paid for. Still, it is better than the current situation. At least such officers will be a financial liability for their departments.
