Preamble
Congress OF THE United States
begun and held at the City of New York, on Wednesday
the Fourth of March, one thousand seven hundred and eighty nine.
THE Conventions of a number of the States having at the time of their adopting the Constitution, expressed a desire, in order to prevent misconstruction or abuse of its powers, that further declaratory and restrictive clauses should be added: And as extending the ground of public confidence in the Government, will best insure the beneficent ends of its institution
RESOLVED by the Senate and House of Representatives of the United States of America, in Congress assembled, two thirds of both Houses concurring, that the following Articles be proposed to the Legislatures of the several States, as Amendments to the Constitution of the United States, all or any of which Articles, when ratified by three fourths of the said Legislatures, to be valid to all intents and purposes, as part of the said Constitution; viz.:
Articles in addition to, and Amendment of the Constitution of the United States of America, proposed by Congress, and ratified by the Legislatures of the several States, pursuant to the fifth Article of the original Constitution.
IOW, when they ratified them, they became part of Art 6 para 2's "Supreme law of the Land" the "Laws of any State to the Contrary notwithstanding".
What Roscoe/Mojave is talking about is an old argument about Nunn V State. Some of Roscoe's fellow gun haters didn't like it that Southern blacks were carrying concealed "coach guns" to protect themselves from lynch mobs and such. I agreed that a State could mandate that it's militiamen bear their arms in certain ways, either concealed, or openly, but they they could not prohibit carry altogether. Since then, he uses that argument to try and paint me into a corner. It never works, but he keeps trying...
"No free government was ever founded, or ever preserved its liberty, without uniting the characters of citizen and soldier in those destined for the defense of the State. Such are a well regulated Militia, composed of the freeholders, citizen, and husbandman; who take up arms to preserve their property, as individuals, and their rights as freemen." - James Madison, United States Congress, Bill of Rights Ratification, 1779 (NOTE: also attributed to Richard Henry Lee, State Gazette (Charleston), September 8, 1788)
Some smart old guys those Founders. They would have drummed people like Roscoe out of town while coating them liberally in tar and feathers...
