The question remains is this: Will the state of Mississippi come to the legal defense of it’s citizens when they violate a federal gun law?
That would seem to indicate that the feds would be conducting arrests inside the sovereign state of MS and any county sheriff can run them off since he is the TOP LEO in the county. Unless of course the state has ceded that level of authority. Since the fed laws would be invalid in MS, the case could be made for false arrest.
No...the question is: Will Mississippi ban the ATF from its state? Anything but that is effectively meaningless!
Now we need someone with a CNC machine and alot of 80% receivers to manufacture MS-only machine guns and hope their is enough money behind the inevitable ATF killing, confiscation, and litigation.
So here's an interesting thing about that: since CO and WA have legalized marijuana, the number of federal prosecutions in the state have gone down. The Federal government has deliberately cast a blind eye to marijuana laws. This, I believe, sets a precedent that would lead to one hell of a SCOTUS showdown if the feds ever tried to go after a MS gun owner if/when this law passes.
This is very brave of MS and a shot across the bow of the federal government leviathan. If we can get more states to follow suit, I believe we'll have a "mandate" to get the feds out of gun ownership altogether, which would set the media ablaze in apoplexia.
Remember, the Second Amendment is an enshrined RIGHT. It is not transferrable, non-revocable, not debatable. It is clearly a right that we enjoy and that "shall not be infringed." If the feds go after MS for passing a law that directly addresses and affirms an article in the Bill of Rights while casting a blind eye to a federal regulation on the sale and possession of a schedule I drug, I believe it would be the arena of SCOTUS to finally say what the 2A means. If the feds can attack a right in the BoR, what can't they attack?
