But whatever we do, we'll never stop every mass shooting. I've said before, as one of my father's Secret Service men once told me, "You can't defend against the crazies."
Alexis in Navy Yard, as well as Holmes in Aurora, Harris at Columbine, and many other mass shooters, were crazies. They each had serious mental problems.
Did they turn violent because they were naturally psychotic, or were they twisted by the side effects of the powerful anti-depressant drugs they were taking?
Could their rampages have been prevented by better medical care, better ways to keep guns out of the hands of crazy people, more armed guards in public places, or by ending the gun-free zones that attract young men bent on mass murder?
I don't know if any of these common-sense methods would prevent or reduce future mass shootings. The Idiots Against Guns in government and the mainstream media obviously don't know, either.
But they don't want to find out. For them it's always the gun that's to blame -- even when it doesn't exist.
