What is there to Debate?
Sounds to me like the Air Marshall plan worked as designed. To some though, mostly of the 'touchy feely' kind, this is disturbing. What is disturbing is that there are people, my guess they are not in law enforcement, who believe more time should have been taken.
Rep. John Mica of Florida made the right call on this "Air marshals don't have time for counseling or interviewing passengers. They have to make split-second decisions based on the current threat".
When a perp is reaching into the bag he/she says the bomb is in, you don't give them time, you give them lead. Some are claiming that maybe he could have blown the bomb after he was shot, which may be true, everything is a risk. But when make split second decisions, the Air Marshall had to decide which is a bigger one, him living and probably blowing up the bomb, or him dying and possibly blowing it up. Probably is always more dangerous than possibly.
I went through a weapons and tactics course once, the "final exam" was a stress driven course, 100 yard sprint to 4 stations using 3 firing positions, with 14 rounds each station, 4-7 possible perpetrators, and less than a minute to complete it, and they jammed 2 guns in different ways. Every perp got double tapped when I went through. So did a cardboard cutout of a kid.
I wasn't worried about 100 passengers, myself, or anything else, and I still made a bad decision on a shot, I can't imagine how much more stress that Air Marshall was under yesterday, his decision was real life, not cardboard cut outs.
