A friend who does drug counseling suggested addiction as soon as she saw the video of his return. Since he had left camp numerous times before his last AWOL its always possible the Afghanistan soldier he was friendly with were actually his dealers. Wouldn’t be the first addict that walked away from an acceptable lifestyle for the addicts life!
Actions have consequences!
I always thought Bergdahl’s rapid eye-blinking in that video was very strange. Did your friend mention anything about that?
