Adam Lanza couldn't have committed the Sandy Hook massacre if he didn't have an Assault Weapon. That's what politicians and the media tells us. Actually that's also what I was told by an acquaintance last week. One has to wonder why some people still believe this. I suspect that their emotions are over riding their logic on this topic.
I'm sure that the massacre was made a lot easier by his choice of a weapon that used normal (30 rnd) capacity magazines, but in reality just about any firearm would have worked. He could have used a Glock, and had a pocket full of normal 17 rnd magazines. Even 10 round mags would have been sufficient.
To be honest, Lanza could have used a 5 shot revolver and a pocket full of speedloaders. It's not like he was facing a lot of opposition.
The killer fired about 150 bullets during his killing spree. Even if he had used ten round magazines, the body count would have been the same. I doubt that the children would have rushed him during a reload.
The AR looks scary to many uninformed people, but it's clear that this weapon wasn't needed for the massacre at Sandy Hook. A 100 year old M1911 with the normal 7 rnd magazines would have done the same job. A Glock or even a J frame .38spl would have worked. Adam Lanza could have used Joe Biden's shotguns and gotten the same results.
For some reason the anti gunners believe that inconveniencing a shooter and making him reload a couple of extra times is going to stop mass killings.
Adam Lanza wasn't successful in his murder fantasy because he had an AR15. He was successful because he was unopposed.
