The only problem I had with the interview was it was sensational as opposed to informative. He basically acted like
a schoolyard bully, with a television audience as his gang. I only listened to the audio the first time, and wondered, "Why is this guy getting airtime?". Only later did I realize there were snippets of info about what made him special being flashed at the bottom. I would have liked the interviewer to mention some of the stuff he did, like take pictures of kids and put them on the internet, and create a website that shows people how to "enjoy" kids and the best places to do it. That's the big danger and the central issue to his being on TV in the first place. If he wanted to warn us about him, and inform us about him, then tell us why he's REALLY dangerous.
Anyway, the bigger issue here is the law and a few different ones.
If you have someone pose for a picture, you are required to get consent from the model or the model's guardian. But if someone was in plain view, which means they are visible publicly, consent is not required. The concept of plain view is important in order to have a free press.
Sadly, this guy is taking advantage of that law.
The other issue is that as long as he doesn't commit a crime, he can't be put on a sex offender database. He can move anywhere and not be put on a Megan's law list. He can talk about it as much as he wants, but you can't bust him until he does it.
You can't nail him for solicitation either, since he's not technically encouraging others to commit a crime. Although, he is making opportunities and temptations for other pedophiles to assault a kid, if he doesn't encourage it, he can't be nailed for solicitation either. But if anything, I think this is the legal aspect than can be interpreted against him.
I don't know if changing the laws would work anyway, as it would ultimately affect our personal liberty.
Maybe lynching him would be easier.
