Okay, I will. The problem wasn't lack of armed guards, the problem was a mad man with a gun. It isn't a big risk this is a statistical improbability. Likely not to occur again, why spend the money? It will not bring the dead back to life.
I am sorry, it just seems like it is to late to place armed guards around the school.
I am sure the parents are telling themselves they wish they had been there, I am almost certain they would have taken a bullet for their kid. Perhaps some of the fallen didn't want to go to school maybe mom and dad made them, i an certain they wish they haven't
What I an saying is that hind sight is 20/20, do we guard every theater, every air plane, every building every mall? Is that rational is one guard enough? Should they be tactically trained, should they have a gun at school? For what a very very very unlikely event?
There is nit enough man power, not enough money, there is not really enough trust worthy people in the world willing to work for that small of a salary. Schools are under enough burden with trying to teach children the skills they need to worry about volcanoes, earthquakes our even less likely mass shootings.
My sympathies go to the survivors, my prayers go to the fallen, but the reality doesn't change because their kid died in an unlikely event.
