Thanks the the contracts police unions get from local governments, it's not only hard to get rid of violent, corrupt cops, but investigating them in the first place is made nigh-impossible. They beat, steal and grift with impunity. The New York Times' editorial board says it's time for legislators to rip up these agreements and force the rule of law on those who represent it.

Across the country, municipal governments have signed contracts with police unions including provisions that shield officers from punishment for brutal behavior as well as from legitimate complaints by the citizens they are supposed to serve. That may soon change, as public outrage over police killings of civilians is ratcheting up pressure on elected officials to radically revise police contracts that make it almost impossible to bring officers to justice. The most striking case in point is Chicago, which has been roiled by a police scandal stemming from a cover-up in the case of a 17-year-old named Laquan McDonald, who was executed by a police officer nearly two years ago.

What's changed? Even old white folks are becoming scared of the cops. If it shows just how bad this problem has gotten, it's also a bitter reminder of what it takes to get something done about it.
