That's what I thought.
What happened to Lori Berenson is similar to Walker's situation, except for maybe the evidence of weapons.
Also, I don't know if he has... probably not since he's being sent back to the states, but what if Walker denounces his US citizenship? Then again, there are 'rumors' that he has given some 'vital' information about Al Quaida and the Taliban to US authorities.
Ok, I'm done thinking out loud and disecting this one.
