Federal Air Marshal shooting

I feel safer already. Yesterday, some guy stood up on a flight already on the tarmac and said he had a bomb. The Federal Air Marshals who were on the flight told him to get down, but when he didn't listen they shot and killed the man. When the man first got up and starting freaking out his wife was yelling that he was bipolar and didn't know what he was doing. I think the Air Marshals did a fabulous job taking the man down. I feel sorry for the wife, but if he was prone to outbursts like the one displayed yesterday, why wasn't the flight crew informed? Also, why is Katie Couric asking the if the Air Marshals could have just shot to wound instead of kill. According to Ms. Couric, normal people were wondering why they had to kill the man. I'm sorry, but if it's me on the plane and some guy jumps up and goes crazy, I want him put down and not simply wounded. What if the guy was a terrorist and really did have a bomb like he claimed? If only wounded, would he still be able to detonate the bomb? It's crap like this that makes me crazy. Also, from what I've heard, it's extremely hard to simply wound a person. The part of the Hollywood film where the star only wounds happens only in the movies Katie. When a person is identified as a terrorist threat, the officers shoot to kill and I'm glad they do so that people like you still have an opportunity to make an asshat out of yourself.
