The thing that gets me is that these people can have multiple investigations with a true finding for sexual abuse, as this guy does, and if you now the right place to look, you can access the information, but without a criminal prosecution, they don't go on the sex offender list, so all they have to do is move to another state and start over. The chances of them getting caught, or at least prosecuted, are virtually zero without an unqualified confession, and even then, they get left walking the streets because "we don't have anywhere to put them."
Here in NY and NJ, a guy caught molesting children -when caught and prosecuted- can stand to be prosecuted worse than a serial murderer.
And sometimes they cop a plea and get off lightly.
