He also had vintage photos that could be (and were by the police) considered child pornography. That's probably more important than the porno theater incident.
It was undercover detectives that "caught" him and they didn't approach him until he tried to leave. They also arrested 3 other people.
Who ever volunteered to watch these guys cum in a porn theater just to handcuff their slimy wrists... I'm no comedian, but that entire situation is so insane I feel I could do at least 10 minutes on it.
