Besides that, law enforcement doesn’t protect anyone. Didn’t protect Brian Thompson, did it?

Law enforcement is reactive. They show up after the crime has been committed to take notes (incorrectly) and maybe arrest the wrong person. Oh, except when patrol officers are running speed traps so they can intimidate the undesirables and shake them down for fines (which are regressive), maybe abuse some authority (or just make shit up) in order to provoke an unnecessary arrest.
