I really dont think that the fear of getting shot is keeping them out of the flight deck , first thing is they have no fear, they are fanatics they will blow them selves up for no reason, and second if a aircraft is taken over again you think that the the proper miltary dept wont be called? you having a weapon on the plane means nothing to them when you have 3, 4 or 5 people rushing the filght deck I dont care if you are a crack shot you cannot get that many shots of and kill all the intruders while sitting down before you are beat down so
