Well, Kenessaw passed this ordinance back in the early-80's (The Dead Milkman even ridiculed it in a song). So we have decades of actual real-life experience to compare to the fictional anecdotal stories you invision. The experience in Kenessaw simply doesn't play your scenario out. Literally an entire generation has been raised in this environment. So before you render all innocent people defenseless, it would be more helpful to supply facts rather than posibilities on the fringe of reality that fly in the face of who actually perpetrates gun violence. Just because the husband snapping and using a weapon splashes across the news for days and 23 murders in Chicago in one weekend goes relatively unreported doesn't change the nature of gun violence in the real world.
