New submitter phrackthat writes with news that California State Senator Leland Yee (D-S.F.) says he wants regulations to track who owns and uses 3-D printers. Yee's comments come in response to the recent news of Defense Distributed's successful test-firing of a 3-D printed gun. "He's concerned that just about anyone with access to those cutting-edge printers can arm themselves. 'Terrorists can make these guns and do some horrible things to an individual and then walk away scott-free, and that is something that is really dangerous,' said Yee. He said while this new technology is impressive, it must be regulated when it comes to making guns. He says background checks, requiring serial numbers and even registering them could be part of new legislation that he says will protect the public. Yee added, 'This particular gun has no trace whatsoever.'"
