He hired a lawyer to try and get out of his army contract.
A lawyer? Man he really wanted to get out of the army, just theoretically, is it possible that he was feeling his hate towards American was increasing and he figured if he could get away from the army it might decrease? Afterall, since he managed to rise to the rank of Major, it's obvious that this is not simply some Islamic nutter, obviously this is/has been an intelligent person.
There's so many possibilities right now, I hope the official inquiries into the whole massacre gets the relatives of the deceased some answers.. Why, and how, could this happen in the most modern army in the world?
