I literally know next to nothing about sandy hook but you need to realize there is always a way to come up with a crazy alternative theory. It's totally fine to claim the sky is orange if you think there is good reason to believe that the government sprays an aerosol that changes the light cones in your eyes or some other nonsense. I think I've heard shit about actors or lying parents? It doesn't matter if you think there's no evidence, they will definitely come up with detail after detail to defy that point and my point is that it's basically never "it happened or it didn't"; conspiracies are the systematic denial of whether something happened a certain way or not. It's almost tautologically wrong to claim there is only black or white when you step into the hypothetical world of such thought experiments, and as crazy as I agree that most of those theories are, I think it's dumb to make your arguing point "there is no opinion on this, it's definitely 100% the way I say it is". That doesn't get you anywhere philosophically.
