Finnish neo-Nazis 3D printed guns

*Finnish neo-Nazis used 3D printer to make guns in preparation for "race war".*

Home-made guns are now a serious danger. I think it is valid to criminalize possessing one.

However, the British approach of making it a crime to have a copy of plans for 3D-printing is an injustice.

To make the mere possession of a copy of something — whatever it might be — is an injustice because it puts everyone in danger of being set up for prosecution.
