My old man was a NYS BCI Investigator, did his 20 and got out. While he was there, some highs and lows- he was Roy Roger's and Liberace's bodyguard, and he was Troop A, Batavia for a while, which meant he was at Attica- in fact he was the guy firing tear gas out of the helicopter into the yard before the assault. Never had to fire his "real" gun at anyone. But he did tell me, when I was 16, "I don't care what you decide to do with your life, just promise me you won't be a cop- the stuff you'll see and be expected to ignore and cover up will drive you nuts"
Between that and the human factor, meaning that a few folks who have no business being cops sneak through the screen, a little discretion on your part goes a long way- and no matter if you did anything wrong in the first place, if a cop tells you to do something and you don't, you've just become wrong. Better to go with the program, hope there's a (credible) witness, and pursue it later.
We had one in particular here in town that never should have been, spent a few years as a motor, and had MANY complaints from women he'd pulled over that hadn't done anything, and pressured them for $ex to get out of a bogus ticket, etc. Had done a little Golden Gloves, and was always trying to pick fights in bars, etc. Made such a bad name for himself that the other blues got sick of him, he was really just a lousy excuse for a human being. So he's in a crowded, popular local restaurant one Friday night, has a couple, gets arrogant with a friend of mine who's sitting with his family, and hauls off and hits my buddy, laughing whatareyagonnadoaboutit hahaha... A couple other friends, both well-known and respected contractors in town, grabbed him and drug him outside, laid him across a car hood, and beat the he// out of him, and most of the patrons came out and cheered. One of the guys called my first friend's (the guy who got hit in the first place)son-in-law, who happened to be a PD Sergeant, to come and get his drunken a$$hole cop that had tripped and fell down in the parking lot. He came down with a patrolman and scooped up Mr. Tough Guy, after checking out his FIL's cut cheek, got a few witness statements, "yeah, he hit that guy over there and then fell down", and went downtown and started the paperwork
