There was a recent case in Illinois where the district attorneys' office decided to create their own private police force that wasn't covered by any of the laws normally reserved for law enforcement, so it could do whatever the fuck it wanted.
I remember one guy they hired to sit and pull people over all day on the highway who said the same thing "I can find something wrong with every single vehicle that passes by. I can literally pull anybody over that I want." IIRC he had things like a corner of a mudflap being broken off, or some trivial insanity like that. The big one in Illinois was having any air freshener hanging from your mirror.
