Well, since you found it necessary to say twice, maybe you should be asking yourself, "How difficult was it for the gunman to kill all those people?" If the answer is, "It was very easy." then perhaps the present day protection methods are inadequate......er.......possibly deadly in themselves.

And, yes, running to a predetermined safe place would make the darling little targets harder to hit. Of course the way to keep the damage to the absolute minimum when the firing takes place is to rush the gunman as a unit.....put him/her down and kill him/her if necessary.....swallow your fukn fear and do it.....for the kids.
