WASHINGTON, D.C. – Attorney General Karl A. Racine announced today that he joined a coalition of 21 Attorneys General suing the Trump Administration to stop it from allowing 3D-printed gun files to be released on the internet. These files would allow anyone to 3D-print unregistered, untraceable firearms. These untraceable firearms, sometimes called “ghost guns,” can be very difficult to detect, even with metal detectors.
