I don't know the specifics of this case, but I don't see how anybody would be a policeman in this current society.
My wife and I were discussing it the other night. Low pay, having to deal with thugs and miscreants that want to kill you every day, dealing with domestic situations that should be handled by what most consider "adults". All of those things, and they try to hang you when an incident occurs like this one.
No way. Hayul naw. Ain't happening.
