Now you're back into the realm of accidents, which is as bullshittery as the car analogy.
You can be hit by a meteor and die. That doesn't mean the meteor was created by Lex Luthor for the purpose of killing you.
Attaching emotion to it is on you; when you're trained for military or police work, they'll do what they can to remove that factor, but you plugged that element in here yourself. I'm simply clarifying a definition. Definition doesn't require a value judgment.
Bottom line remains, sitting on the internet trying to claim guns are for "sending projectiles" and not for killing is dishonest bullshit. Firearms were invented for hunting and for war,
both of which mean killing, which is the firearm's exact
purpose. If it didn't do that -- then there would be no point in taking it to the hunt or the war. Not ******* rocket surgery. Let's cut the bullshit pretense.
Nor did I say a gun is designed "only for killing people". Obviously some are desiged for killing animals. Some are designed for killing planes in the sky. Broadly speaking (torpedoes), some are designed to blow up ships. All of them are designed for some kind of destruction.
If they do a "piss poor job", then it's curious that it's the overwhelmingly dominant choice for the mass murder epidemics we see.
And maybe that's the answer after all -- let's see if we can convince the Harrises/Klebolds and the Holmses and the Lanzas and the Loughners and the Pages that "don't bother, you'll do a piss poor job". Rotsa ruck with that.
