The problem I have with cops is there's virtually no accountability with them. Most of the time, whenever they fuck up, at best they do an internal investigation which usually results in "we have investigated ourselves and found that we did nothing wrong". They rarely try to even get rid of the bad ones because its basically a fraternity with guns. The few good ones who actually try to make a change with in the department and repot the bad ones usually end up getting pushed out. And when they are in the act of doing something terrible, theres really nothing you can do to stop them because if you intervene then you'll either get arrested or shot, all you can do is film them and hope they don't kill the person they're attacking, hell even filming them could put you in danger.
