U are so full of crap. Police assaulting non cops without cause occurs everyday across the nation. Having a tough job doesn’t excuse malicious and violence against innocent people.
Of course it doesn’t, but the number of incidents where cops assault people (as you put it) is miniscule compared to the thousands of cops who do a difficult job every day of the year.
Considering the stress of the job and the crap they have to put up with, I’m surprised cops manage to have such self-control the majority of the time.
