History

Historical Context

In May 2013 Defense Distributed posted the Liberator’s CAD files, which were downloaded more than 100,000 times in two days before the State Department ordered their removal. The open-source gun sparked lawsuits and a 2021 Ninth Circuit ruling that limited online distribution of such files. The use of a 3-D-printed, silenced firearm by Luigi Mangione to shoot UnitedHealthcare CEO Brian Thompson revives those regulatory debates.
