John Wayne Gacy was a politically connected man and I think his day gig was construction contracting, not being a clown. That was a kink in and of itself.
Charles Manson was a habitual criminal who tried to make it as a singer/songwriter in the land of the freaks (first SF then LA) and roamed in the circle of influence with Neil Young and the Beach Boys. Reputedly the Manson Family even participated in some of the Hollywood celeb orgies of the swinging 60s. He let his coven know of his plans for violence. It was an era of outlaw culture celebrated in the popular media, whether it was Hell Angels and other black leather bikers, Black Panthers, or other Communist revolutionaries building bombs, carrying guns, robbing banks, shooting cops, and causing riots.
Wasn’t Ted Bundy a lawyer (who’d studied hypnosis and other talents of mind control)?
Add to that list Jim Jones, another politically connected pervert left wing radical.
No. As an undergrad he talked of going to law school and he chose to represent himself in at least one of his trials but he was never a lawyer.
