Although some laud Heller for recognizing an individual right to some arms, its false standard allows Congress and the states to ban arms they and the courts claim are not “common” or that are useful “in military service.” As Breyer put it, “On the majority’s reasoning, if tomorrow someone invents a particularly useful, highly dangerous self-defense weapon, Congress and the States had better ban it immediately, for once it becomes popular Congress will no longer possess the authority to do so.”
Breyer was mocking his colleagues, but “tomorrow” is important because firearms are near the end of their 500-year era of usefulness for the military purpose the Framers intended. Notwithstanding gun-control supporters’ complaints about the supposed new-fangledness of this or that firearm or firearm accessory, firearms are glorified slingshots.
Three thousand years ago, David slew Goliath with a rock ballistically comparable to a .45 caliber pistol bullet. Gunpowder propels a bullet more predictably than a whirling leather thong, but bullets, like rocks, are inert projectiles.
