He didn't look too injured in the pictures. I wonder if being admitted to the hosptial was some sort of ruse.
About the only thing that would absolve the US administration of guilt in their handling of this Saudi, would be if the Saudi was part of a US spy ring. They have to protect him then. He could be double agent, but the feds must not suspect that. Otherwise this is Obama justifying that Golden Necklace investment to his homie.
