"Although the Supreme Court has held this Amendment to include only arms necessary to a well-regulated militia, as so construed, its prohibition is absolute."
(Black, Hugo, The Bill of Rights, New York University Law Review, Vol. 35, April 1960.)
As Stephen Halbrook correctly pointed out, under the "collective right" version of the Second Amendment, the Supreme Court would have dismissed Miller's lawsuit against the Feds due to obvious lack of standing.
They would have explained that Miller obviously had no 2A rights and should have never been allowed to assert a claim for 2A protection in the first place.
