I hate to rain on the parade, but we should be very careful with this chained guy. It would not be hard for a senior terrorist leader to have himself so positioned so that the Americans would think he's a victim, his bona fides need to be checked out thoroughly. Keep him in a nice military hospital until we are certain we know who he is and have with certainty eliminated the possiblity he is a terrorist.
I am suspicious as well. If he was kidnapped a week ago, why is his beard still neatly cut along his neck?
Bruises can also come from flying mortar and cinder block - as US MArines destroy the building you are hiding in.
If he is legit, God bless him. If not, remove his ta-ta's and send him home.
