Just published today this article reports the opinions of politicians on the the manufacturing of plastic weaponry via the use of home 3D printers and the bill to make them illegal. For those that do not know a 3D printers are able to print objects out of molded plastic; even objects with such complexity as that of a gun. . They can pass unnoticed by metal detectors and can be easily printed at home by a (relatively) cheap printer at the price of 4000 dollars. Seemingly the perfect weapon for a would be terrorist. Not only that but with the power to create a such a weapon at home unnoticed, any and gun control laws would be nullified.
After reading this i'm not sure if a bill could ever be strong enough to stop the plastic guns without interfering with the 2 amendment
