This interview with gun activist Cody Wilson questions how printable firearms may change the dynamic of political power. Wilson fired a shot heard around the world when he created The Liberator, a plastic pistol he made on a 3D printer, and then put the 3D-printing files (or CADs) up on the Internet for free. To folks interested in cutting-edge technology and decentralized experiments in living, Wilson's gun symbolized an age of uncontrollable freedom. To lawmakers, it symbolized a threat that moved faster than a speeding bullet. The State Department, in fact, shut down the ability of Wilson's non-profit, Defense Distributed, to disseminate the gun files on the Internet, claiming it was violating federal rules about exporting munitions.
