The guy is a genius at what he did no doubt about it. Given what he did was illegal and unethical which he fully acknowledges. Last I heard he was running his own consulting firm whereby he teaches his clients how to avoid becoming a victim of fraud.
In the accompanying clip he is on a game show and people have himself and two other people that are posing to be him. They are answering questions and at the end the contestants of the game show attempt to guess who is the 'real' Frank Abagnale. I find it interesting that when the game show is over the only person that wasn't suspected of being the 'real' Frank was in fact Frank.
This speaks volumes towards most people's ability to detect deception.
