What Curious Aardvark said, but for every UK, read Australia.

And the media hype about 3D printed guns is just that, hype. Actually it's ill-informed, grab-at-a-straw, unresearched bunkum. Just like every light airplane that is involved in a flying incident is a Cessna, not matter what the truth might be.

A dissertation, essay, or whatever about the 3D Printing of guns is best suited for submission as an English Literature work of fiction. You'll get better grades and your work will make more sense.
