P.S.

In reflecting upon my previous post, especially after hearing a bit on NPR about 3-d gun printing, (http://m.npr.org/news/front/171154845) I thought I might add the following:

Some of the pro-gun outrage is only in response to theoretical limitations. Some people who don't want gun laws to change might not even own guns currently; just the idea of having unfettered liberty augmented (whether or not an augmentation would have practical implications for them) seems to be enough justification to prevent any action being taken that can actually have practical benefit for people, including in the face of re-curring (and potentially preventable) tragedies. How can this be acceptable?
