Obama: Deniability Man

This operation was a setup. The Pak Army knew enough to clear the ground and the air. Otherwise, all it takes is one guy with an RPG to blow up a helicopter that's flying low enough and slow enough to land and take off again. It might take 15 minutes on the ground to do the job, and you're a sitting duck for UBL's bodyguards and random soldiers. So this had to be coordinated with all the big players on the ground. It's like a Chicago mob hit: Everybody knows except the target.
