We saw a Dr. Phil show about child predators that made us ill. He even stopped the tape. It had to do with undercover cops, and what they have to do to bust these inhuman creeps. After stopping the surveilence tape, Dr. Phil asked the detective if it was hard not to reach across the table(he met the creep at a restaurant), and knock his teeth out.
Las Vegas police felt they couldn't wait, so they busted the man before the FBI was ready to move in. I may have trouble remembering numbers, but I'll never forget what was said between the cop and that scumball.
Montel Williams has had some pretty harsh programs on the subject, as well.
