Calling the shooting a "watershed event" in the national debate on gun control, Cerberus Capital, a New York-based firm that manages over $20 billion, said in a statement Tuesday it planned to sell off its investment in the Freedom Group. Freedom Group bills itself as a "family" of more than a dozen firearm companies including Bushmaster Firearms. Officials said it was a Bushmaster assault-style rifle, the civilian version of the military's M-16, that 20-year-old Adam Lanza used in a majority of the rampage that took the lives of 20 children and six adults at Sandy Hook Elementary School Friday morning.
