Well, actually, I think it’s entirely possible, yes. He accessed guns that are legal in the USA but quite illegal, say, in Canada. They were accessible to him solely because a family member had purchased them legally, and for reasons we will never know, left them accessible to a son she knew had mental problems.
Had those weapons not been legal, it is entirely possible Nancy Lanza would not have bothered to acquire them, and Adam Lanza, who would then not have been living in a house with an arsenal of firearms, might not have seen these easily accessible weapons as a means to his bizarre end.
Of course, it’s possible Adam Lanza would have gone to the trouble of acquiring the weapons himself, and had be been successful, we might be in the same situation. It is theoretically possible he might have found some other way to kill people. But I think it very likely that the simple availability and proximity of the weapons was a part of his decision making process, and that had they not been there, the awful switch in his mind that went to “murder” might not have flipped, or had it done so, his actions would not have killed as many people. Perhaps had he had access to nothing more than a knife, he would only have killed his mother, an awful thing but only 1/27th as awful as what happened. We’ll never know for sure, but it sure seems like a possibility. I mean, I think it is pretty well understood by now that when you have a hammer, things start to look like a nail. It’s human nature to frame the solution to problems in terms of the tools at hand.
Whatever you think the relative possibilities are in the Newtown case, it seems obvious to me that if you multiply them across the thousands of gun murders in the United States that at least some would not have happened had the weapons in question been harder to obtain.
It certainly is interesting that Americans have more guns than almost any other First World country and shoot each other more than almost any other First World country. It seems exceedingly coincidental, if there is no connection there.
I don’t know what the solution is, truth be told. I don’t know why Americans are so prone to shooting each other, to such a bizarre degree. Four times likelier than Canadians, I believe, despite being in so many other ways so similar to us. I so fervently wish you find a way to fix it. I love the USA, and want the best for you.
