The point is inapposite; it only begs the question of regulation of firearms under the Second Amendment.
Miller did not hold that regulation was prohibited under the Second Amendment, it held just the opposite. In
Miller, the Supreme Court upheld the National Firearms Act against the challenge that it violated the Second Amendment. That is the
ratio decidendi of the courtÂ’s ruling in
Miller, which is binding precedent. The relevant point is not whether a particular weapon meets the
Miller test; but rather that it is nevertheless subject to regulation.
