Was Bowe tortured? I do not know...
What I do know is that a relatively healthy young man walked to the awaiting helicopter. If the torture had been unrelenting and ongoing, Bowe would have looked gaunt/frail at the handover. He would not have walked upright without any hint of injury.
Caught a YouTube video of the prisoner handover at the end of the Vietnam war. The one where John MCCain is returned.
Every man was at least 20lbs underweight. It was obvious that none of them would be running a marathon anytime soon.
Those men had been tortured. That is what the effects of torture looks like.
Bowe needs to work on his limp a bit more...
Take some time and compare the release footage to the various videos shot of him while in captivity, you will see he is very gaunt in each one of them.
In any case, the exchange deal was being worked on for months and just like the Soviets did with their prisoners, the Afghans made sure Bowe Bergdahl did not appear mistreated in front of the cameras. After all, this is a propaganda film we are watching, not just some news reel.
