They, too, might have left trails of shattered lives and broken families similar to those we now read about in towns where children have become killers. I raise these questions not as an anti-gun nut. Decades ago, in a prior professional incarnation, I was trained to use a .38-caliber pistol and .357 Magnum. I know how it feels to carry a loaded weapon on your hip. I also recall the awesome, destructive power of those weapons.
Children have no business with handguns.
Neither, for that matter, do most adults. So let's do something about it. Get to work on abusive school environments. Look for warning signs of a troubled student, and get the child help. Beef up school physical security where necessary.
