This comic is strictly of the "in my dreams" variety as any good Amurkan who actually gets a gun waved in their face is much more likely to run out and buy a bigger one to wave back rather than encourage legislation to curb such nonsense. Actually, "double-dreamy" as the U.S. Congress fears the American gun lobby more than death itself.
As a result, America is well on its way to the Assault Weapon Event Horizon. Not only are we destined to be legally required to walk the streets armed with the minimum of at least one fully-automatic weapon, but in the near future all domestic industries will be devoted to weapons manufacture and all stores will sell nothing but guns.
We will drive guns, we will live in guns, and we will eat the softer variety of guns. We'll have gun sex and have gun babies. All important decisions in law, government, or economics will depend on who shoots first and who's left standing. (This law already in effect in Somalia, Rwanda, and Florida.)
It will be a bullet-operated world, not unlike the one we live in today, until the National Hand-Grenade Association catches a few prominent politicians in compromising situations. Then we'll see some really explosive Second Amendment action.
