A shotgun was removed from the trunk of Adam’s vehicle, at night oddly enough.. The question is, why would Lanza use a long range rifle to kill children 30 feet away when he had hand guns in his possession? Oh that’s right, it’s the long range ‘assault weapon’ rifles that the gov’t wants to ban because those are the ones THEY fear the most could be used against THEM. So it’s only fitting that Lanza would use the rifle, otherwise 0bama would have to act to ban handguns and that’s a less realistic door opener to banning all guns.
Could also be because that is what he had the most ammo for. The shotgun would have been a better choice and really made a mess
Why? Because it was /is a great tool to kill people with. 30rd mags, simple operation, can be fired easily, low recoil, etc. The AR-15 is a nice tool. That's why.
It could be something as simple as he was most familiar and comfortable with that particular weapon. I don’t believe the 0bama regime caused the Newtown shooting, but they have surely capitalized on it. They are absolutely responsible for the murders of Brian Terry, Jaime Zapata, and God knows how many Mexicans.
