One of the Harry Potter actors was killed by a young man weilding a knife. Of course, the British government blames the incident on the knives, instead of on the kid who was using the knives. The rhetoric sounds vaguely familiar. Oh, yes, that's it. Replace "knife" with "gun" and you have the anti-gun movement in the USA.
People, inanimate objects don't kill you. Psycho's kill you. You can take away guns, knives, forks, and pens from the populace, but then the criminals will still have them. And Joe the psycho from down the street? He'll kill you with a rock if he has to, he's not picky.
