It turned out that Zamudio actually pushed the holder of the gun into a wall, and thus came much closer to doing violence on an innocent man who had just taken the gun from Jared Loughner than even this description suggests. The potential for yet another innocent death was pretty high here. And a Wild West show with alternating bouts of gunfire seems like an extremely dangerous environment for bystanders.

Frank Lautenberg said it very clearly on MSNBC: the difference between this country and practically every other industrialized nation, which has a tiny fraction of the gun violence as we have in the US, is that “we don’t have more madmen, we have more guns.” And increasing the amount of armed people out there won’t help this ratio, either.
