What gets me is that, let's suppose, he has been having sex with children for a LONG time. Now, wouldn't he have enough "fond" memories, or have enough porn, from prior trips?
You can bet that this was not his first rodeo.
I think that the more and longer they get away with doing it, the bolder they get and the more their appite grows.
You would be safe in betting that he is a hero among his peers on campus.
Pedophilia is not all about sex; it's about power.
"Power over", specifically.
Generally these people can't function sexually with people their own age/size.
[and if they manage to, you can bet they're thinking about their last child victim, when they do]
They literally get off on the terror and helplessness of little children.
These kind of people would have to stand on step ladders just to look the lowest dregs of society in the eye.
I'm sure search warrants have already been executed for his homes, boat, cars, offices, bank vaults, etc. He was sloppy enough to get caught with video in his personal possession, so he's probably sloppy in other ways as well.
