Re: Why a 3D printed gun?
I suspect the ten years in jail (UK law) if caught with it probably would have a deterrent effect though.
And yet it doesn't. People still get shot in London all the time (24 last year), by proper guns and converted blank firers or historic weapons too. I can't really see why if the threat of jail time doesn't deter folk from that that it would with a plastic gun. Maybe not carried every day, but collected and deployed when intended to be used.
