It is good to remember that the Federal Government takes Jurisdiction over firearms
under the Interstate Commerce Clause. If a gun is made in one state and the powder/cap
is also made in that state,then it is under the Jurisdiction of State Law. If nothing is
shipped across state lines then it is State Jurisdiction. The Federal Jurisdiction is
extremely limited but rarely tested. Having said that, the States often have stricter gun
laws than the Federal Government. Jurisdiction is key. Whenever a gun enforcement
action is taken, the Court involved will require a legal basis for the Jurisdiction. In the News
now, we see Texas stating that they have the Jurisdiction to build a wall and protect their
borders. There is, in law,the doctrine of dual sovereigns, and the Tenth Amendment makes
Texas correct. Texas has that power,the Supremacy clause pertains only to what the Constitution
places under Federal Jurisdiction. The Founders never intended for Interstate Commerce
to apply to guns,only to Taxation and duties. Remember the first Federal Gun
control was caged as a "Tax". There should be a greater focus on Jurisdiction. Everyone just assumes that whatever Government wants to do is legal--not always.
