It had to be Bergdahl. The Afghani boys knew that this was a strange bird, an anomaly and went to tell the soldiers what they saw.
Court martial the bastard and then death by firing squad. That would be the perfect world though.
There is talk that Bergdahl LEFT A NOTE to his squad members telling them that he was deserting and that he will not fight for America any longer.
We need to produce that note as evidence IF IT EXISTS.
