Worst grade school shooting: tough gun control?

Democracy Now!:

Police say the Newtown gunman, 20-year-old Adam Lanza, used a semi-automatic Bushmaster assault rifle, similar to the M4 carbine used by the U.S. military. He also had two handguns, a Glock 9-millimeter semiautomatic pistol and a Sig Sauer. The massacre occurred just miles from the National Shooting Sports Foundation, the nation’s second most powerful pro-gun lobby in the country after the National Rifle Association. We host a debate on gun control between John Velleco, chief federal lobbyist for Gun Owners of America, and Christian Heyne, legislative assistant and grassroots coordinator for the Coalition to Stop Gun Violence. We’re also joined by Paul Barrett, author of "Glock: The Rise of America’s Gun."
