(Providence, RI) -- Rhode Island is joining a lawsuit aiming to stop 3D-printed guns. Attorney General Peter Kilmartin says Rhode Island will join ten other states attempting to stop what he calls an abrupt policy shift from the federal government to allow the distribution of firearm designs for reproduction using a 3D printer. Kilmartin says the move creates a public safety crisis by allowing the mass manufacture and distribution of illegal and untraceable firearms that will end up in the hands of criminals and terrorists.
