Summary: On Tuesday, the Supreme Court denied an attempt by Remington Arms to block a lawsuit filed by families of the victims of the 2012 Sandy Hook massacre, who argue the maker of the AR-15-style rifle should be held liable for its marketing of the military-style weapons. Robert Spitzer, author of "Guns Across America," joins William Brangham to discuss what the decision means for firearm manufacturers.
