The syllabus for U.S. v. Miller, which was written by staffers rather than any of the justices, says that the Court found the Second Amendment only protects state militias; at least one lower court cases cites language which appears in the syllabus but not in the actual decision in finding that the Second Amendment only protects state militias. It is unfortunate that the U.S. Supreme Court has been unwilling to take cases which would overturn the syllabus.
That's not my recollection. Can you provide details?
