For the Sep 700 puts, presuming they were bought for 0.05, if SPX drops to 1400 and Vix pops to >30, those puts could be going for 0.10. Both the spot price and VIX have been at those levels recently. Not the way I would trade a down move, but I think it's more likely a Taleb like person made the trade rather than Bin Laden through his Etrade account in the mountains. Better yet, perhaps Bin Laden called the trade desk at TOS and got them to get his trade filled at a favorable mid price.
