This can make the entire gun control debate pointless: student/inventor Cody Wilson has successfully designed and tested a pistol that can be easily downloaded through the internet and made into reality using a cheap 3D plastic printer by anyone. One push of a button and bang, you are done. It's called The Liberator and it will be the first of many. In a few years, people will be able to print AK-47s at home, no background checks, no questions asked. Good luck, everyone. [Gizmodo]
