Fascinating
That's the kind of story that a geek like me wants to believe. I would love to help question him. My reasonable nature tells me it's BS but I question whether it is possible to get access to enough insider info to turn $800 into $350 mil in two weeks.
One way to check would be to ask him the names of his family as far back as he can remember and check dna. Of course the location/fate of OBL would do nicelly.
