I agree with you, I wish the Second Amendment HAD remained intact and untouched. Only it hasn't. For close to 200 years the SA was seen as ceding control over firearms to state authorities. It was interpreted as meaning the federal government could not interfere. The Scalia Court turned that meaning on it's head.
I believe in local control. If a rural county in Missouri or Iowa wants to grant to any citizen who hasn't been convicted of a felony the right to own and carry a gun that's fine. Or even an entire state such as Florida. At the same time if New York City and the suburban counties want to use special conditions to restrict carrying -- on the notion that the more guns that are out there the more chances there are that somebody will get shot -- I think we should have that right. And for the past one hundred years we have had that right.
Even the Scalia Supreme Court is backing away a bit from the idea no locality can restrict handguns. Maryland enacted a tough gun control law. Under it an applicant for a handgun permit must demonstrate
"a good and substantial reason," they can't just say, "I want to carry a handgun for self-defense." The Second Amendment Foundation -- the same people who litigated
Heller and
McDonald -- appealed this law all the way to the Supreme Court. Last October the Court declined to hear the appeal. The story from a
Baltimore Sun article published last October. So maybe the pendulum is beginning to swing the other way.
