They were also hitting them a while back, sometime last year.
RIP CIA drug source. (1 of them anyways)
Alwaleed was not let go. He has no money or freedom of movement.
He is a hostage doing the bidding of the 'Patriots' now. Alaweed being our puppet gives us complete control of his investments ( and more) without causing further drama.
His time will come in the future. For now hes just a pawn.
