In this Monday, Feb. 4, 2013 photo, founder of Stop Handgun Violence, John Rosenthal, addresses an audience as board member of Gun Owners Action League Steve Moysey, left, looks on during a panel discussion called "Made in America: Our Gun Violence Culture" on the Emerson College campus in Boston. Rosenthal advocates requiring background checks for all gun purchases and banning sales of military-style rifles. A military-style rifle "was used to kill babies in Newtown and now everybody wants it," Rosenthal said. (AP Photo/Steven Senne)
