Batman used to carry a gun. It's true. Back in the 1930s, not only did he carry a gun, but he killed bad guys with it. The very first official "Batman" comic featured the Caped Crusader firing a machine gun. But the public grew uneasy. So the editors adopted a new rule: no guns for Batman. Bob Kane, the character's co-creator, would later explain that his editors worried "that mothers would object to letting their kids see and read about such shootings."
That tale from a simpler age comes to mind as, once more, we cringe at the ease with which carnage can be inflicted by a determined shooter. We've long passed the point when parents can shield their children from seeing and reading about horrific violence, whether or not inflicted by guns. And reports about violence — especially terrorism — frighten them.
A lot.
If children are scared, what do we tell them?
Do we say, "Don't worry, there's no chance of a terror attack or a mass shooting in our neighborhood?" If we say it, do we believe it? Do the children believe it? Moral panics don't lend themselves to rational analysis.
Do we say, "Despite what you might see on television, the rate of gun violence in the U.S. is down?" I doubt that will do any good. Children are as vulnerable as anyone else to the availability heuristic — probably more so.
Do we say, "The government has matters in hand?" We can try, but we'd be lying. This is an era, after all, when the left thinks the problem is too many guns and the right thinks the problem is too many bad people, and we can't even discuss policy without an eruption of mindless savagery in the Twitterverse. And most children, by a relatively young age, have likely heard enough political fury in their own homes to get the point that government isn't working very well just now.
Do we say, "Let's pray for the people who got hurt?" Well, if we happen to be praying people, we might try. But see the previous paragraph, about the mindless savagery of the Twitterverse: Apparently, people who don't believe in the efficacy of prayer are really angry these days at people who do. (I'm betting the kids already know that, too.)
