Fry, you’re really not thinking this through far enough. This ruling could finally guarantee an individuals constitutionally given right to own a gun. If they confirm that, as well as strike down the ban, states lke NY will quickly find themselves in court over their pistol permit laws that make it almost impossible for a good citizen to have a handgun.
As with most Supreme Court cases, the real issue is not the specific case at hand but the interpretation of the law they’re going to have to define to reach a decision in that case. That interpretation will become the basis for all cases going forward, and in the case of individual gun rights they have never really issued a decision like this before.
