I know personally about 5 cops and you are 100% correct.
They are thugs and have a street gang mentality and would roll you and beat you mercilessly for next to nothing.
Protect & Serve? YEAH RIGHT.
I recently took a CCW class from 2 former cops. Both said that for a cop it is all about how you present things in your report. You can do anything and get away with it if you present it right because you are presumed honest.
It was disillusioning to those of us who assume cops are honest.
