Question comes as a kind of addition to one I asked awhile back. It was about having met a truly evil person. I can tell the story again if anyone is interested but as a young teen I interacted with a guy in the Aryan brotherhood from California several times.
Not that I’m aware of. I’ve known some shady characters, a few went to jail for robbing a gas station. I don’t know of anyone being extremely violent, but that doesn’t mean it didn’t happen.
