Great news!
Of course it just absolutely sucks that we have to jump and cheer, and question how or if the federal government will stick to the Constitution.
NOTE: The 2nd amendment was just that - AN AMENDMENT - not only does it #1)articulate and protect a natural right, it is a change to the Constitution, in this case one which #2) overides anything previous in the Constitution that would infringe on the right to keep and bear arms...especially a clause the does not explicitly give Congress that power...the State commerce clause included.
The government having to rely on its commerce powers to regulate arms - specifically their manufacture, possession or their use, is obviously an encroachment into the people's right to keep and bear them. When 3/4 of the States ratified the 10 out of the 12 proposed Amendments, they agreed that what is known as the Bill of Rights would amend, and become part of the law of the land,...PERIOD! (until subsequently amended)
