Japanese police arrested a 27 year old man called Yoshitomo Imura, alleging that he 3D printed several guns and posted videos to Youtube of himself firing it. They say they seized five guns from Imura's home in Kawasaki City. The videos showed that two of these guns were capable of firing rounds -- what sort isn't specified -- through a stack of ten sheets of plywood, and this caused Japanese police to class them as lethal weapons. A Japanese press account has Imura admitting to printing the guns, but insisting that he "didn't know they were illegal."
As I wrote a year ago when 3D printed guns first appeared on the scene, the regulatory questions raised by them are much more significant than the narrow issue of gun control. But there's a real danger that judges, lawmakers and regulators will be distracted by the inflammatory issue of firearms when considering the wider question of trying to regulate computers.
According to ANN News, Yoshitomo Imura allegedly downloaded gun blueprints from a foreign site and then printed the resin guns with his 3D printer.
Imura had apparently uploaded videos to YouTube in which he fired off what looks to be a 3D printed pistol. Last month, police seized five 3D printed guns from Imura's Kawasaki City home.
