Most of us may not know exactly what he did or what was in his head, but that is part of the problem in today's society. NO ACCOUNTABILITY!!! He needs to and will be prosecuted under military law. His rank will be reduced and he will be either be put in the brig or dishonorably discharged. If this is a "war" then hopefully he will be put in brig or maybe even death. He deserted his unit purposely. He knew exactly what he was doing. Even if you are a regular soldier you know what the military is about, that is all you train for. This isn't some surprise. BY HE WAS NOT A REGULAR SOLDIER, he was Special Forces. Where they train harder and are trained to kill. By deserting his fellow soldiers he put himself in danger, but also put his fellow soldiers in danger and many of them died because of it.
As far as debriefing goes, my guess is that we will not get much out of him. More than likely the enemy got more out of him. Is it just me or does every picture and video of this guy, NOT HAVE A LOOK of someone that regrets what he did, or does it look like someone who was content with his decision and he was being treated humanly. Every other time that I have seen an American "Prisoner of War" they have had some sort of look of terror, some type of a sign or torture or maybe even starvation.
