It was pretty ballsy for the authors of "Five myths about gun control" to use an Ozzy Osbourne quote to try to prove that the adage "guns don't kill people, people kill people," is a myth. "If that's the case," they quote Ozzy, "why do we give people guns when they go to war? Why not just send the people?"
OK, Ozzy. Deep breath. Setting aside the absurdity of your argument, its corollary actually disproves your point. If a warring nation dropped weapons onto a battlefield--without also deploying soldiers--they would simply be giving the other team a timely gift. It's possible that an M16 dropped onto an enemy combatant's head might kill him. But that rifle couldn't jump out of the plane on its own. It would need a little help, proving once again that guns--by themselves--do not kill people. You need people for that.
Lesson: If you're trying to be cute, make sure you're also right.
