"How do you explain the 2 year delay on your CV?"
Depending on who he's explaining it to it could be the high point of his CV.
"Clearly not a danger to anyone and most probably learned from his mistakes so what could he have done to piss off the authorities?"
We know what he's done to piss off the authorities. He's shown up a whole lot of very senior US officials as being completely crap at managing their own security and inconvenienced them into tightening up, possibly to the state they should have been in all the time. And not only that, he could do it while not even being bright enough to avoid being caught.
