~1,400 Americans are killed by government police every year, and there are thousands of incidents fitting that description just in the last twenty years:
Cops, regardless which agency they burble forth from, are increasingly unwilling to respect anyone's right to life, liberty, or property.
The paid vacation given to cops after police assaults and killings is basically "paying a bounty" for civilian beatings and murder.
The main obstacle to reform is that government police face zero liability and are often given awards and raises for assaulting and killing people. These amount to powerful incentives to behave in ways that most people would normally never consider.
The culture must change, and no human/civil rights commission will change it. As long as police get a government paycheck, there is no incentive for police to respect anyone's rights.
