Is there much threat to the public when the weapons "are stored in the Washington County militias concrete and steel vault"?
Plus they're stamped with the word non-commercial". How much safer can you get?
That point will be at issue in court, no doubt.
There is no doubt of course, that a 'well regulated' militia can keep arms; -- or there should be no doubt.
You never know tho in FReeperland, as many of our loudest mouths claim that fed, state or local governments can prohibit any arms they choose.
