Some of us may remember Bert the Turtle, pictured above. He cheerfully urged students of our schools to "duck and cover" in case of nuclear attack during the early days of the Cold War. That consisted of diving under desks and covering heads with arms. Thus, the effects of nuclear explosions were avoided, Bert (and presumably his creators) told us. Perhaps some of the flying shards of glass and debris which might have resulted would have been blocked by desks and arms, but it's unlikely that incineration would have been avoided in any significant sense, and if anyone survived radiation would have served to eliminate them despite Bert's wise recommendation.
But perhaps ducking and covering would be more effective against bullets than against ICBMs carrying nuclear warheads. Clearly, the possibility of students being shot by someone carrying one firearm or another (it seems semi-automatic rifles are the most popular weapons of choice currently) is far greater than was (is?) the possibility of nuclear war. Perhaps we should bring back the Duck and Cover drills, and it's to be hoped improve on them, this time in an effort to foil people who use guns to kill other people. Guns, as we know, don't kill people. But it seems undeniable that some people who have guns do kill others, particularly here and now. People use guns to kill people.
A Renaissance of Duck and Cover drills or something similar is probably all, and likely more, than can be expected in response to the most recent mass murder. Fantasies of owning guns to prevent the tyranny of government aren't what inspire objections to gun control or an absolutist interpretation of the Second Amendment. It is, very simply, a question of money. As long as money can be made manufacturing and selling guns here in our Glorious Union, the so-called gun control debate will continue to be meaningless and unproductive. That people, even children, are shot has become part of the cost of doing business.
It's possible that technology soon may allow each of use to manufacture our own cheap firearms, in which case profits from making and selling guns will diminish. Then the politicians who are mere shills for the gun and ammunition industries may be less inclined to do their bidding. But in that case we'll all have guns, men, women and children, or easy access to them, and control won't be a practical possibility.
But perhaps that's the goal, ultimately, of those who admit of no restriction to the ownership and possession of firearms. They look forward to the day all will have guns, or perhaps when all must have guns.
