Why doesn't Paul make a deal with the American law, if it was him I would go to the court asking how many got accepted to the settlement "it is probably way lower than 11300 BTC" go to jail for a year after giving like 9000 BTC's back and after one year he goes out with 2300 BTC's and he can actually walk free around he's own country meeting he's own family? That's of course if it was him + he has the wallet.
Why on earth would he do that?
Right now, he gets to live out his life in another country without spending a year in jail, and if he still has the keys to the stolen bitcoins he could spend them all, any time he wants.
I just thought of something. It's possible that in all of Paul's haste, he accidently rid the private keys with no chance of gaining access to the loot, hence opting for another heist not as lucrative but highly profitable nonetheless.
Unless he's a total fuckin idiot in wanting it all, he's original plan may have been to sit on the original stolen loot, then organically close down Cryptsy with minimum repercussions on his part. But when/if the mega loot was lost, he had to plan and implement another heist.
