Look, I grew up on an Oregon farm where guns were a part of life; and my dad gave me a .22 rifle for my 12th birthday. I understand: shooting is fun! But so is driving, and we accept that we must wear seat belts, use headlights at night, and fill out forms to buy a car. Why can’t we be equally adult about regulating guns?

And don’t say that it won’t make a difference because crazies will always be able to get a gun. We’re not going to eliminate gun deaths, any more than we have eliminated auto accidents. But if we could reduce gun deaths by one-third, that would be 10,000 lives saved annually.

Likewise, don’t bother with the argument that if more people carried guns, they would deter shooters or interrupt them. Mass shooters typically kill themselves or are promptly caught, so it’s hard to see what deterrence would be added by having more people pack heat. There have been few if any cases in the United States in which an ordinary citizen with a gun stopped a mass shooting.

The tragedy isn’t one school shooting, it’s the unceasing toll across our country. More Americans die in gun homicides and suicides in six months than have died in the last 25 years in every terrorist attack and the wars in Afghanistan and Iraq combined.

So what can we do? A starting point would be to limit gun purchases to one a month, to curb gun traffickers. Likewise, we should restrict the sale of high-capacity magazines so that a shooter can’t kill as many people without reloading.

We should impose a universal background check for gun buyers, even with private sales. Let’s make serial numbers more difficult to erase, and back California in its effort to require that new handguns imprint a microstamp on each shell so that it can be traced back to a particular gun.
