It is highly unlikely that we'll see one of these mental cases use an FAL, an M1 Tanker, or an M1A, in a mass killing. You have to be a thinker to buy, use, and care for anyone of those weapons. You have to be skilled to make them work for you. Those aren't things these kinds of mental cases bring to the table or want to have to bring to the table. The AR15 doesn't demand those requirements. That's one of the reasons it's so dangerous.
One of the main differences between us and our closest relatives, the Chimpanzees, is the level of cooperation between members of the species. Ours is quite high, theirs, in comparison, is quite low. Banning the AR15 is about cooperation between members of this highly evolved society we have. This society is based on abstract thought and then brought to fruition via cooperation.
You, like the mass murderers, fail the cooperation test Sirs. You are a Chimp.
