Wrong Zack, the answer is that he Bludgeoned his victims to death. At least thirty of them. He wanted to kill, gun or no gun. He liked it. You think Ted Bundy was unstoppable, but the Sandy Hook killer was?? Where's the logic here Zack?
And Again, How would any of the 23 points have stopped Sandy Hook? You still haven't answered that.
All I've said I support are the resources being granted for researching root cause and effectiveness of laws on the books, the laws on the books being uniformly applied, and efforts towards better enforcement (with the exception of simply making harsher penalties as I don't feel they're an effective deterrent). If these laws are already perfectly uniform across the states, as you seem to be saying... what exactly are we arguing about?
We have to learn more about why these events happen in order to take effective action against them. Since there seems to be little unbiased research in this area... again why is this something to oppose? Both sides of this, pro and con, need good information to base their positions on. Otherwise it's guess and guess/gut against gut, and the only way we find out what works is by examining if more or less people die. Hardly ideal.
Requiring training or storage isn't part of this. Though I would support that because as you have said, they're very easy to use. I think that makes them easy to misuse with tragic results. I fear somebody with no respect for their weapon firing a gun in a backyard with my kid present more than I fear some gang takeover or serial killer coming across my family's path. Though, I'm happy to concede this to you. I don't know for sure either way, and again... part of why more research into these events is something I happily support. So that we can have more to go on than "yes it would/no it wouldn't", hypothetical gang hostage situations, and Ted Bundy.
I haven't blamed anybody for anything.
What would you suggest get done to prevent this sort of incident in the future? "Nothing can be done" is not an acceptable answer at all. If we don't have the info now to make that kind of decision. Then at the very least research should be done to try and get it. That appears to be getting done, and I'm very pleased about that. Maybe it will turn up something and maybe it won't, and that is the very nature of research. It's no reason not to try.
