Trouble getting a gun? Just print one:
An American gunsmith has become the first person to construct and shoot a pistol partly made out of plastic, 3D-printed parts. The creator, user HaveBlue from the AR-15 forum, has reportedly fired 200 rounds with his part-plastic pistol without any sign of wear and tear.[...]... the interesting thing is that the lower receiver — in a legal sense at least — is what actually constitutes a firearm. Without a lower receiver, the gun would not work; thus, the receiver is the actual legally-controlled part.
In short, this means that people without gun licenses — or people who have had their licenses revoked — could print their own lower receiver and build a complete, off-the-books gun. What a chilling thought.
On the other hand, guns don't kill people, printing presses do.
