It is clear that the NRA's approach will not work. Committed shooters will find a way into schools. They will not be deterred by the presence of armed guards, as the NRA contends. An armed guard was present at Columbine High School on the day of its horrific shooting in 1999; he did not cause the attackers to alter their plans, nor could he stop them. As for Sally Ports, attackers can bypass the front entrance and shoot in a window. Should we board up all school windows, then? Or buy still more "state-of-the-art" security instruments for our schools — such as bulletproof whiteboards, backpacks and blankets? Will the NRA finally tell us, in light of enduring security shortcomings, to equip our schools with whole regiments of guards, outfitted with bulletproof vests and assault weapons? At what point do we register the cost to the educational experience of our children, the impact on their impressionable psyches and the damage to our democratic society?
