There have been efforts over the years to establish such a provision, Senator Mountjoy was involved in the efforts as I recall.
Unfortunately, such efforts were hindered by Constitutional know-nothings who would claim it wasn't needed because of the 2nd Amendment.
It seems to me that that approach would tend to bring into focus, even for non-gun-owners, what the real issues in this situation actually are.
On the subject of the SC, I think it is a little bit ludicrous to believe that each of the 20,000 gun laws currently in existence today, not a single one has been found to be unconstitutional. This sounds to me more like SC un-cojones-ability than infallibility (or some kind of legislative miracle). Without questioning the fine print legalities of the matter, I read this as incentive for the common citizen to BLOAT, "big-time". And I don't see how any reasonable person could conclude otherwise.
