If he has not already done it, this is the next FOIA request on John's list.
Others in his unit present on the days he disappeared paint a picture that he deserted. UCMJ defined AWOL and Desertion as up to 30 days you are Absent with out leave. After 30 you are declared a deserter, but I am not sure how that standard is when you are in a combat zone. Did he just get stupid one night and wonder off for a day and end up captured while being AWOL, or did he desert deliberately and collaborate with the enemy. His Father also had posted some controversial comments on twitter that have been taken down, something to the effect of Gitmo detainees and the US killing Afgan babies. He and the son had exchanged emails a that were controversial.
Last but not least, 6 people have died in efforts to find this guy after he disappeared. I would not want to be in his shoes, and hopefully Obama is not fool enough to try making anykind of hero out of him. But Obama already has made a photo opp out of this, diverting the attention away from another failure of the VA system. Seems to be a common tactic of Obama's.
