One of the proposals being discussed after the Parkland high-school shooting — and touted by President Trump — is to have schools protected by arming teachers, hiring armed guards, or otherwise allowing or requiring the proverbial “good guy with a gun” to be on school grounds. Naturally, this idea has attracted a lot of rage and scorn, much of it from knee-jerk dislike of guns and/or Trump. Some have compared it to Archie Bunker arguing that all the passengers on an airplane should be given guns (a satirical proposal that goes to show nobody has had anything new to say on guns that Archie and Meathead weren’t yelling about 40 years ago . . . but that also would have saved thousands of lives on 9/11).
As with many culture-war arguments, this one could use a dose of common sense. “Arm the teachers” has a role to play in our answers to school shootings, but it’s not a one-size-fits-all solution.
