Story time, so my grandfather was a cop.
He also was a bona fide Nazi, like an actual one in World War II, fighting for the third Reich and everything.
After the war he was looking for a job so (in his words) he “could still beat people up”.
I strongly believe that being able to commit violence without consequence is a strong motivator for many or most people working in “law enforcement”.
We’re all paying taxes in order to arm a bunch of violent psychopaths to terrorize ourselves.
