Physical items are not destructive, people are. That's where you have it all wrong. Gang members will kill other gang members by any means, they don't need guns. Guns, knives, bombs, they don't kill people, people kill people.
The reason is because their POTENTIAL is FAR more destructive and you cannot leave their use up to the whims of an individual with no oversight. That is why we don't! We draw the line somewhere already. So to pretend we don't and that it's all fair game and it's all peoples' fault so it doesn't matter anyway... that's just naive.
Yeah, not really what I meant. But kinda cool!
