Are some child molesters naturally "creepy" looking?

You ever seen a guy on street, and said to yourself " I wouldn't leave my kids with that guy" And just look at the guy that admitted to killing JonBenet. Doesn't he "look" like a child molester?? I don't know, maybe it's just me. And I would wrongly never accuse someone of a crime based on their looks. But I would be careful, and that is my choice....
