It is living and breathing in the sense that it can be amended, but not in the sense of being malleable.
Short of banning all guns, I don't know how you use gun control to stop crazy people from going onto school campuses and shooting the place up. Armed school personnel might be an answer. That's how they do it in Israel and they don't have this problem despite being surrounded by enemies who would love to do just that. Might add that they have secure borders.
Having an honest discussion would be a good first step. Biden told at least two whoppers during his recent speech on the matter.
1. Biden falsely stated that though someone who buys a gun at a gun store has to go through a federal background check, there is an exemption for sales made at gun shows. That is flatly untrue.
2. Another lie Biden told was when he declared that the gun industry has special protection from all liability. No such exemption exists.
