The Constitution doesn't *give* the RKBA, it protects it.
"...the right of the people ... shall not be infringed".
Now that said, The One would likely federalize the Alaska Guard, and send in the BAFTErs anyway. Of course the Guard might not choose to *be* federalized for such a purpose, and the BATFers might be sent home with their tails between their legs, like the jackals they are. As you can see, the existence of the right is *assumed*, and the Constitution says that it may not be infringed.
They had a little discussion about that 150 years ago.
The feds won.
