You are right, cops don't "go postal" very often.
I don't accuse all cops because a few cops abuse their authority.
But I do accuse the cops who are complicit in coverups of that abuse.
As do I. Look, covering up criminality goes against everything they swore to abide by.
This idea that ‘wink wink’ we’ve got each other’s back, is a sick twisted mentality. When the chips are down of course you have the other person’s back. Not when it comes to beating charges you both know you’re guilty of.
