Advocates of gun control like to believe access to firearms will become more difficult if the government restricts legal access. Perhaps this was true at one time but guns are, mechanically, simple devices and the equipment to manufacture them is becoming more affordable every day. Behold, the first (to my knowledge and the knowledge of the creator) firearm manufactures on a 3D printer:
As 3D printer technology becomes more affordable gun control will become more pointless. The obvious solution to this problem, according to gun control advocates, would be to place tight restrictions on 3D printers. Fortunately such controls would be equally pointless because there are already people working on do it yourself 3D printers. One the genie is out of the bottle it cannot be put back in.
