It's much worse than just "hotdog" cops. Police are now sadists. They are NOT your friends.
I used to handle 42 USC 1983 cases for a national insurer whose primary business was public entity (school boards, police departments, municipalities, etc.). 95% of the 42 USC 1983 cases were against cops. Our role as the insurer was, of course, to defend the cops in the civil actions brought against them. Even if the claims against them were groundless, I can tell you the majority of the cops we defended were complete a$$holes, with chips on their shoulders that were the size of 2 x 4’s. They were even snarky to us, and we were defending them in court! I tell you, it was a rude awakening.
