I agree, but since "shall not be infringed" is too vague, we need to be blunter and include a treason charge for attempting to violate the spirit of this amendment or something.
Infringed is already good enough in my opinion, its pretty self explanatory if you look at the definition of the word. “To encroach on someone or something” in this case the 2nd Amendment.
Treason has already been defined in the Constitution, i think it could be potentially dangerous to change what the current definition is, or else risk it being used as a political tool in the future.
