Some of them. In my direct experience, the number who've behaved that way is 0, though.

I think taking the worst of the police that are findable in a whole country's worth of bodycam footage, and then assigning blame to every single police person based on those people, makes about as much sense as a policeman putting on an "ASAB" patch for "all suspects are bastards," because a certain subset of the people he encounters are pieces of shit, and then deciding that every single person on the "other side" that he interacts with is the enemy.

I mean, some police do do that. I don't think they should. I don't think either that every single person who chooses to do a vitally necessary job for a living becomes the enemy the instant they decide to do that.
