Yep, you are correct Doc.
As an example a former Sgt. then Bailiff here was just busted by the feds for kiddy porn on his computers. Knew the guy for years and never had a clue. He was a fixture at the local gun show at the fair grounds for years trading buying & selling. He also did DJ work at local events and campgrounds.
He got caught in one of the "honey trap" sites that tracked back to his IP and of course him.
