Normal people can do horrible things in the wrong circumstances especially when the group mentality takes over.
First off saturation squads like SCORPION are there for aggressive policing. They confront people in high crime areas and make lots of arrests. Anyone see a problem as to how that can morph into something not so good? They do help reduce crime, and in fact this crowd was recently lauded for their crime reduction efforts. They also produce plenty of EF claims like the guy selling loosies in NYC.
Secondly, did you see a police supervisor during the beating? I didn’t. You had five patrol officers left to their own devices in a saturation squad. No way that could go wrong.
Thirdly, I would bet the house that their training on this type of policing was woefully inadequate.
I laugh at the notion that the female police chief was some type of policing progressive.
You can’t train or supervise basic humanity. But you can do a lot to prevent this type of thing from happening.
