How are you going to get proof, when our feral government has already whisked the guy safely back to Saudi Arabia?
The point is, too much circumstantial evidence points at this guy to rule him out as a suspect. By that very fact alone, the government should have hung onto him until all of the investigations into this thing are complete.
Rushing him out of the country like they did, only further deepens suspicions of hanky-panky at the very highest levels. It's known that Kerry and Obama met with Saudi VIPs just prior to this guy being rushed back to Saudi.
I'm sorry, but that just stinks to high heaven.
And do we know that he was deported? I heard he wasn't.
