Congress should tell states, in the wake of this surely worse epidemic of gun violence, that they must put some substance into the phrase “well-regulated militia.” They must define well-regulated militia to include not only the National Guard, but all legally registered gun-owners in the state. If they fail to do so, and in line with the precedent set by the drinking-age act, they risk losing 10 percent of their federal law-enforcement funding.
Why not? Who could argue with such a move? It would be precisely in the spirit of the Second Amendment as worded, in which the right to keep and bear arms is granted within the context of the existence of such a militia. The founders spoke explicitly of said militia. So, let’s make it!
Legally registered gun-owners would become members of each state’s more broadly construed militia. They would not, obviously, be required to report for service on certain weekends like Guard members do. But their membership in this broader militia would come with certain responsibilities.
First, they could be obliged by law to keep their guns in a locked, steel safe to which only the registered owner has access. They could also be obliged to undergo certain testing and evaluation before being permitted to own certain kinds of guns—or, depending on the state, barred from owning certain types of guns at all, or barred from keeping them at home (that is, they could buy and own them, but they would have to keep those guns at the firing range, which after all is the only place where they can be legitimately used).
Obviously, hunting rifles would not be covered here under any circumstance, and maybe the federal law could even state that explicitly, so that legitimate sportsmen could rest easy and the National Rifle Association wouldn’t be able to play that card. Congress could toss a few other little sweeteners into such legislation—for example, it could subsidize the purchase of steel safes for a short time, much as it is about to subsidize the purchase of health insurance. Something tells me conservatives wouldn’t caterwaul about this subsidy so much!
