From The Business Insider:

It’s a gun. It works. And any nut with access to a 3D printer can print one in the privacy of their bedroom and then … well, you get the picture. The plans include a metal shank so that it’ll show up in an x-ray scanner, but it is the work of moments to remove it. And while it is an argument that has a different resonance in the US, where any aforesaid nut can simply go out and buy a gun in a shop, and the rights of nuts to go and buy such guns is enshrined in the constitution, even there, it has caused shock waves. In Britain, where we hope our robbers carry nothing more than a big stick and arm our police officers accordingly, it’s a potential societal revolution that none of us asked for.

One must remember that the interviewer is from England and hostile to most of Cody’s ideas and most of The United States’ ideals as well.
