I'll drill down even deeper, It's not a police problem, it's a people problem. These people just happen to have guns and batons and the authority to use them if they deem it necessary. The bad people just use them in evil ways.
I disagree. I think it's a police problem because as C-Rock mentioned, there's not a lot of accountability within the police force. Yeah there are procedures in place and rules on the books that govern police behavior, but the issue is they don't enforce the standard in their own ranks and often times help cover up each other's dirt.
Like how recently a police chief from a town in Missouri was driving under the influence and was described as hammered drunk. And instead of getting arrested and prosecuted for DWI, his police chief buddy from the town where the traffic stop occurred, swoops in and tells the officer that made the traffic stop that he was just going to drive his friend home, and give him a stern talking too.
There have also been quite a few instances where good cops try to intervene and stop fellow officers from being abusive and the good cops are the ones who receive backlash for crossing the blue line.
Also, before body cams became the new standard, it was pretty much second nature for officers to "massage" arrest reports to justify their actions.
That's why I think it's more of a culture issue and not just departments hiring the wrong people.
