The fact that people instantly go to both-sidesing this is absolutely infuriating. This isn't some kind of red-team/blue-team dynamic bullshit sports thing. Police officers are the designated empowered representatives of the state and they absolutely must follow the law. There is no rule of law if they can beat your ass and kill you and then hide behind a wall of denial, a police union, unaccountable processes, and phalanx of defenders like this.
Police officers die in the line of duty. Yep. It's a dangerous job. You know who else dies in the line of duty? Truck drivers. Truck drivers die at 2x the rate of police officers in America. Do they get a free pass for beating the shit out of people and killing them? Hell no.
