Professor Volokh, linked left, with his fellow bloggers has been covering the case where a gun owner, or wishes to be a gun owner, is challenging Washington D.C.'s ban on gun ownership, D.C vs. Heller. The arguments for gun ownership and, even perhaps more, in clarifying the meaning of the Second Amendment are fascinating. If you can only read one, I recommend Lund's which is linked in this Volokh post. The JFPO, Jews for the Preservation of Gun Ownership amicus curae brief linked in a Volokh post is also fascinating. I believe you can see the related posts by going to 'related posts' at the foot of a blogpost.
