In 2008, in District of Coumbia vs Heller, the Supreme Court ruled that the right to keep and bear arms extended to all “federal enclaves,” but left the question open as to whether Article II applied to all states and cities as well. Today, the Supremes ruled 5-4 (opinion written by Justice Alito) that it does, and the practical result is that many of the more demented state and city gun laws in the U.S. are going to be challenged in court, and probably beaten.

This could not possibly have come at a more fortunate time because, with the election of Elena Kagan to the Supreme Court, the legal climate there is going to change for the worse. Ms. Kagan has spent her life shuttlng from Princeton to Harvard to Oxford to Harvard Law School, and then back to Harvard Law School as Dean, to government service in Washington, D.C., and if she had spent the time in a convent, her knowledge of real life in the United States could not be more limited.

I doubt that Justice-to-Be Kagan has any concept of what it’s like to live on a ranch in southern Arizona, or run a small business in a high-crime district, or inhabit a home where it takes the sheriff a half-hour to get there–if you’re lucky. Or to hunt. Or to enjoy collecting guns, or shoot competitively. And she will decide accordingly.

Let us all breathe a sigh of relief, and send some money to the NRA’s Institute for Legislative Action. They are fighting on your behalf, so give them a hand.
