You can't blame the Air Marshal in this case.Why? As in the
tight confines of the aircraft, in any situation you will only be
given a split second to decide pulling the trigger and a missed
opportunity. On top of that, all military,law enforcement
personnal, when confronted with a situation like this, their brains
literally turn into water and flows out of the ears,and countless
hours of training at the range,snap shooting and quick target
acqusition and evaluating of threat/s just take over.
And i belief, these Air Marshals are actually going through an
emotional turmoil each time they board a flight. They are like
tightly wound springs, just waiting to unleash when the need
arises. And I salute them for that, as nobody who is sane would
feel good pulling the trigger fully knowing that it can kill or
injure another person who has got parents and family like they
themselves.
**just my 2 cents**
