Brady sues over mandatory gun law
Nelson, GA has enacted a law requiring every household to be armed, and Brady Campaign has filed a legal challenge. Since apparently there's no penalty for violation (a feature of the earlier Kennesaw ban, due to some advice I gave decades ago), I have trouble seeing "case or controversy." It would, I'd think, be a chance to trot out Framing era militia statutes, tho.
The Second Amendment's right to arms clause establishes that you may decide how many firearms to own.
Its militia clause, however, recognizes that "none" may be the wrong answer.
