In a court of Law, DNA evidence is a slam dunk proof of guilt. But not in this case involving identical twin brothers.

It's what prompted our entire series of predator investigations: Grown men sending graphic e-mails to young teenagers. And now, it's what has forced a powerful congressman out of office in the scandal that's consuming Washington. Representative Mark Foley of Florida is accused of having sexually explicit online chats with underage teens. Dateline's latest investigation also uncovers some prominent men caught in what police say are criminal acts. They, too, risk losing their jobs... and in some cases, perhaps even their freedom. Again, we want to warn you that some of what you’re about to see is explicit. This report airs Friday, Oct. 6.
