Good point - he’s already violated at least the sprite of the law if not the law itself.
With one possible exception. He will repeal the 2nd amendment if he can find a way. Just for symbolic value. The other amendments are routinely trashed, but they pretend you have free speech as they use government power to suppress it. They pretend you have 4th amendment search protection as they use self written national security letters instead of warrants. That is if they bother with a warrant at all. The NSA goes through your papers at will.
They ignore most of the constitution. But if they can find a way, I think they would love to publically end the 2nd amendment. SO that might be an exception.
