Who is REALLY behind gun control?

There now must have been two shooters at least, and the second one killed Lanza.  Lanza took two handguns into the school.  The Bushmaster – the firearm everyone wants to ban, and the one the coroner said killed all the people – was found in the car.  But Lanza was in the school, dead.  This is very like what happened in Colorado end even to Gabrielle Giffords.
