The more important thing is not the "shock" for the watching audience as it the the "shock" for the dudes busted. Think about it, if everyone in thier family or co-workers, or close friends did not know they were pedophiles, well they do now and they will NEVER look on those people again, and hopefully will never trust their kids with these people.
That is a good thing because the next time these people get the urge they will be fearful of getting busted again so they may turn on young a family member or the child of a close friend to get satisfaction.
Hopefully this is what they need to stop, and if not I hope they knock on the door of a gun owning father who is very protective of his daughter/son.
I personally thought the sick fvck that showed up with his kid was the worst one.
