Thought you may be interested in this article from the Harvard Journal of Law & Public Policy. I was mailed a copy of this issue and, upon reading the title of this article, was immediately suspect. However, I was pleasantly surprised to see such a prestigious journal actually defend gun ownership and cast skepticism on the effectiveness of gun control. I highly recommend reading this article and even keeping a printout handy for any confused friends.
