I don't think I agree with this guy... I'd imagine that people are willing to do many kinds of things if given the opportunity. Not to say that many people would fall for this unless they are sick, but there must be a few examples of witch hunting where the ones who fall for this wouldn't have been able to break the law. However this does seemingly protect kids before the act can be committed to an actual child.
Paedophilia is horrible so I can't really imagine how people are afflicted, but there are other serious crimes that can be brought out of people, such as committing murder for a huge amount of cash or something. At least that's what Darren Brown demonstrated on telly.
I don't know if this is something that has ever been cured or if it is manifested the same way extreme fetishes are (deviant behaviour?), simply because beyond this thread I'm not bothered to do any research in this subject, but public shaming of something I don't fully understand is generally a bad thing to do.
