The theses postulating an inanimate object can cause the violence humans sometime commit upon each other is ludicrous. The concept expounded at such great volume, copiously verbosely and redundantly in the face of all reason to the point where it seems ripe material for hilarious satire, provide abundant fuel for countless comedy shows, acts and reviews to record breaking runs. All of which is precluded because people are actually buying the fiction that an object causes anyone to attack, brutalize, injure, maim and even kill another.
If we remove the human factor from the equation, one might reasonably conclude it more likely a person would be seriously injured or killed by a rock falling/rolling down a hillside than being shot by a weapon alone. IE: the firearm loads points and fires itself.
I admit, I am one who maintains the only impossibility that exists is impossibility itself. Despite the belief anything is possible, I cannot agree that a weapon of any design ever has or will attack anyone. That being the case, when one adds an object cannot cause, make, induce, force, coerce, bludgeon or reason anyone into doing anything whatsoever. It reasonably follows the situation is exactly the reverse. Objects, weapon or not, are at the mercy of human beings. It is always a human who takes up a weapon and makes use of it - never otherwise.
I understand if there were no firearms in people's possession there would be far less drive by, or any other style, shootings. True. I certainly can't argue that. History proves it. Before the marriage of powder, projectiles, a length of pipe and a handle, nobody died of gunshots... But people still died of murder - hacked to pieces, punctured or bludgeoned with the weapons of the time.
Which only proves, it's not the weapon; it's the person that causes violent crimes, attacks, injuries and deaths to occur. It never has been and never will be a weapon of any kind that ever caused an injury or death.
Obviously, it's people, not the inanimate tools people build, that cause violence. Left alone, untouched, I highly doubt a firearm will do more than most rocks ever do. Lay where they are and collect dust; or moss.
