For a couple of weeks now, I have been contemplating a post about the new concept of 3D printable guns. The concept disturbs me greatly, but as yet I was still in the process of researching the technology to better understand it. Meanwhile, tonight I came across a terrific post by fellow-blogger On The Fence Voters, aka Greg, and decided not to re-invent the wheel, especially as Greg has done an excellent job of explaining what they are and whether we should worry … or not. Please take a minute to read this informative and thoughtful post, and also check out the comments, for there is much more food for thought there. Thank you, Greg, for implied permission to re-blog and for this great post!
