Any legislator believes he can pass a state law "exempting" anyone from the reach of the Constitution is too deluded to reason with.
The Federal Firearms Act of '33 was a repugnant "override" of our RKBA's.
Montana's law would partially restore & correct the Acts infringements, -- to the people of Montana.
Laws repugnant to the principles of the US Constitution can be considered null & void, and ignored at any level of government in the USA; -- the burden of constitutional proof then falls to the repugnant 'law'makers.
Any legislator believes he can pass a state law "exempting" anyone from the reach of the Constitution [federal 'law'] is too deluded to reason with.
Montana's law exempts their people from a repugnant federal law, an obviously unconstitutional infringement of the 2nd Amendment.
It boggles the rational mind that a supposed conservative freeper is supporting that infringement.
