If, in fact, the man who was shot was shot because he was mentally ill, then all this equates to is an unfortunate tragedy. If you're an Air Marshal, and some guy starts ranting about having a bomb, you simply don't have the time to determine if he's for real. Something has to be done. As I said, if he really was mentally ill, then it's unfortunate, but you just can't ignore something like that in this day and time.
