All Bergdahl has to do is say, "PTSD" and guess what, that's a get out of jail free card.
The rightwing propaganda machine is already committed to the categorical, unequivocal rejection of the possibility that Bergdahl suffered a mental breakdown.
Why do you say this?
Will Bergdahl not have his day in court?
Will Bergdahl not be treated as
Innocent Until Proven Guilty, at law?
He must now take his chances, with the justice system, like anyone else who acted in the way that he reportedly did.
If he is found 'Not Guilty', then, that's the end of it.
If he is found 'Guilty', then, mitigating circumstances, if any, will be evaluated, for relevance, and depth of impact.
It is now up to the military justice system.
And, if that makes the
Failed Messiah in the White House look worse (
if that is even possible at this late stage in the game), for negotiating with terrorists, in order to fetch-back a deserter, then, so be it.
