You're correct, but I think there is more to it than that. Most people wouldn't do something just because they can get away with it. I think it's that, combined with the lack of morality. I can't remember a time in modern American history with such a lack of morality, and contempt, on the part of government officials at every level.
These are LOCAL cops, that live in these communities. They show a complete disregard for their own neighbors. We're living in very troubling times.
I agree and its a message to the people that the cops are in charge and you better fall into line.
