I wish they wouldn't mix different things. They mention 3D-printed guns first, but then they talk about unserialized frames. You can buy an "80% frame" (basically, the frame of a real gun, but not finished - it still needs 20% of the finishing work done), finish it yourself and add the other parts, and you haven't broken any federal laws by doing so. Though if you sell it, that is a different story - and of course, I don't know what your state and local laws may be. Nothing I've just discussed involves 3D printing. The question being, who is lying to whom here? Are the cops lying to the council, is the council lying to the public, or is the media the one who added "3D printed" just to push the public's buttons?
