Editorial: Here’s a morbid exercise: Can you keep track of which school shooting was the last before Parkland?

If you started typing “school shooting” into Google search Wednesday afternoon, you might have noticed that auto-fill took over and anticipated the next word: “today.” So even the bloodless algorithms within Google recognize that, when one tries to find information about a fresh school shooting, the search needs to be narrowed. Because people are still searching the school shooting from last week. And the one before that. And the one before that. We are six weeks into 2018, and so far there have been at least six shooting incidents on school grounds that have wounded at least one person, including the massacre Wednesday, in which 17 people were reported killed at a high school in Parkland, Fla.

When does an epidemic stop being an epidemic and become just a basic part of regular life? It’s been 19 years since the nation was horrified by the carnage at Columbine in suburban Denver. It’s been just over five years since the Sandy Hook Elementary School shooting. Quick: What was the most recent mass shooting incident (at least four wounded) at a school before the one on Wednesday? Here’s the sick part: There have been so many school shootings that it takes a bit of work to answer what should be an easy question.

Already the folks who support gun control (which includes us) are fuming about the ready availability of firearms in our society. Already the pro-gun folks are pooh-poohing those who think guns are integral to shooting deaths. “Guns don’t kill people, people do,” they like to say. The accurate phrasing should be, “Guns don’t kill people, people with guns do.” At an astonishing rate, a depressing rate, a stomach-churning rate.

As a society we tend to become particularly shocked — at least for a few minutes — when someone shoots down children and young adults while they’re attending classes in what should be a positive, nurturing and safe environment. But even if we’re shocked, we tolerate it. Our outrage is more Pavlovian than visceral. We listen to the bleatings of the gun enthusiasts that, well, if those teachers had guns, then this wouldn’t have been as bad.

Been as bad. Think about that. If a pistol-strapping chemistry teacher had grabbed her .45 and unloaded on today’s gunman after he killed, what, one student? Three? Five? That would be good news?

We do not live in the Wild West. Our schools are not the O.K. Corral. Clint Eastwood isn’t in this movie. We are a violent, disjointed, gun-embracing culture. “But wait!” you might say. “Not me! I hate guns! We need more gun control!” As true as that might be, that’s not the belief of the body politic. Because if it was, we wouldn’t be sitting in front of our television sets wondering what the final death tally will be. Feeling our heartstrings tugged by images of bereft parents. Feeling an impotent rage.

This is what America is today: bloody. The Florida shooting too shall pass, as did Columbine, Sandy Hook, Santa Monica College and so on — all allowed to fade into the backdrop of American memory without a thing being done. This is us. Until we decide finally, forcefully, effectively, that it is not.
