There’s more to it than that. It was pretty normal where I grew up to have guns in the house and accessible. Almost all of my classmates grew up similarly and nothing happened. I’d wager it’s the same in our demographic back then. All those developing brains with access to guns and school shooting were a rarity. There’s other factors that we should be working to identify so that those individuals can get the help they need before they do something terrible.

That’s not to say that gun owners shouldn’t be more responsible about locking them up than we were when I was growing up but we can be doing a lot more than that bare minimum.
