Just make the sale of bullets illegal. Boom, no second amendment problem.
i've been banging this drum for like 6 years. nobody likes it.
how can you argue that bullets aren't protected by the right to bear arms?
I'm not being completely serious, but we should be thinking about bullets in the discussion, especially in the context of "what should we do about the billions of guns currently in circulation?" Sure, if we re-banned assault weapons today it's not practical to try to confiscate all the ones that are currently owned legally, but it certainly would help to cut off the sale of bullets for those weapons as well.
Likewise, now that I think of it, I'd probably add a new tax on bullets to help fund some of the relief/mental health programs we could use. I don't doubt there are plenty of Martha Stewart type gun owners who make their own bullets, but honestly I'm not as worried about those types of gun owners.
