I am one of those terrible liberals who has long-since given up on gun control and mass shootings. The pro-gun sentiment in America—even if it's not a majority—is far too strong to permit any meaningful firearm legislation. Combine that with a pro-gun Supreme Court and I'm unable to see even the slim possibility of any serious regulation in the near or medium-term future. I've never been interested in pie-in-the-sky activism, which is why I don't write much about gun control and don't even think very highly of other liberals wasting their time on it.
But short of serious gun control, are there ways to rein in mass shootings, especially in schools? Yes, but they're minimally useful and all of them are fraught with problems. In this case, it's us liberals who (rightfully) resist conservative proposals because of our concerns over constitutional rights.
So that's my counsel of despair on mass shootings. For the record, though, my own personal proposal for gun regulation is to ban civilian ownership and use of (a) semi-automatic weapons and (b) magazines with a capacity greater than six rounds. This would still permit anyone to own not just a gun, but a genuinely useful gun that can kill people and animals just as well as today's weapons. The only difference is that they're inherently slower unless you're very highly trained. Permitted guns would include things like bolt-action rifles, shotguns, single-action revolvers, and so forth. The gun experts can work out the details, but basically all legal guns would require a separate human action to load a round into the chamber before firing. This wouldn't end mass shootings, but it would cut down the death toll considerably. At the same time, hunters could still hunt and suburban parents could still put guns under their pillows for self defense.
Needless to say, this won't happen. And even if it did, can you imagine how long it would take to confiscate 300 million semi-automatic firearms? The mind reels.
POSTSCRIPT: One of the things I hate most about American gun worship is that it can be kept going only by a campaign of relentless fear about crime. NRA pamphlets and PR campaigns are bursting at the seams with images and statistics designed to convince urban dads that they need plenty of guns along with constant vigilance to keep their families safe from the thugs who stalk our streets and the protesters who threaten to burn our cities down.
Life could be much more pleasant for all us—and less dangerous for many of us—if everyone could get it through their heads that America is a far, far safer place than it was 30 years ago. There's simply no need for the kind of fear that was at least moderately justified back in the '70s and '80s.
Unfortunately, there's a powerful lobby whose very existence depends on making sure everyone believes just the opposite. And they have a media megaphone in the form of Fox News that makes sure their message is spread relentlessly.
In a nutshell, I hate guns for much more than the actual damage they do on their own. But that doesn't change the fact that I can't see any effective way to change things.
