Just a few days ago in my country cops arrested several rich bastards for corruption.

But every single rich bastard is corrupt and commits crimes against the people daily. The fact that very occasionally cops arrest a couple of them and then once in a blue moon maybe one of them sees an actual punishment doesn’t change the fact that the status quo is for those rich bastards and all their rich bastard buddies to live in luxury on the backs of the unfairly compensated workers and that the job of the cops is to enforce that status quo through violence.

And they are not “state sanctioned user of violence”

If I tackled you to the ground, bound you hand and foot, shoved you into my car, drove you to my headquarters and locked you in a cage, you wouldn’t consider that violence? What exactly would it be then?
