My uninformed guess is that this guy had a history. The cop(s) who pulled him over knew him, maybe he had previously done that before, who knows.
The big questions that I want answered, was he being an a$$ when they first stopped him?
Do either of those give law enforcement the right to dole out three cavity searches, and x-ray, and a colonoscopy? It's frightening if citizens now view "being an ass" to a cop a legitimate reason to do repeated cave diving episodes to someone.
