Secrecy is not security. The government will never succeed in trying to keep information from the public at large. Even if you can't download it, it doesn't stop someone from coming up with it on their own. A year ago, I knew nothing about 3D printing. But, I've learned a lot over the past year as I built my own. My experience tells me one thing... there's not a chance that I will ever pull the trigger on a 3D printed gun and risk blowing off the finger that I use to click my mouse. If I wanted to do it though, there is nothing to stop me or anyone else from designing our own and then printing it out. It's all about control and who gets to be in control... of information, of production and of our lives.
