C.S.  let me respond with my post responding to LenG: "

LenG: May I offer agreement. None of our Constitutional rights are "absolute." The limitations on the First Amendment are the clearest example. As you suggest, limitations on the lethality of firearms could easily be enacted. However, it's important to recognize that the firearms industry/NRA lobbying power continues to block any such efforts at the national level. Any congressperson "bucking" the NRA had better represent an extremely "safe" District or he/she will face an extremely well-financed opponent the next election. An unkind, rather harsh person might suggest that some folks prioritize profits over public safety......my regards, Gary Crum"

I'd love to read any defense of 100 round magazines or armor-piercing "cop killer" bullets being sold to the public.  IMO, the strong possible arguments for limitations on any Constitutional Rights are founded on reasonable concern for the public safety.  Is that unreasonable?  GCrum
