"Retailers are pulling back on sales of assault weapons and investors are abandoning gun makers' stocks as the nation's grief focuses on the funerals of the 20 children and six adults killed in the Sandy Hook Elementary School rampage in Newtown, Conn. Calling the deadly assault "tragic and devastating," private equity firm Cerberus Capital Management said Tuesday that it will sell its 95% stake in Freedom Group Inc., which makes the Bushmaster AR-15 rifle that police said was used in the attack. The massacre was a "watershed event that has raised the national debate on gun control to an unprecedented level," Cerberus said."
