This post on 9th Circuit Judge Alex Kozinski, my favorite candidate for the Supreme Court, quotes extensively some writing on gun ownership.
In essence, Kozinski argues against reading certain provisions of the Bill of Rights in a way that expands individual freedom, and others in a way that favors state control. Further, he argues that the possession of weapons by the populace affords some protection against tyranny and genocide.
The guy is conservative in many ways, but really committed to liberty.
UPDATE: There's a movement afoot to send email to firstname.lastname@example.org with something in the title to the effect of "Nominate Alex Kozinski to the Supreme Court." Can't hurt.
Here and here and here, for example.
UPDATE 2: Welcome, Instapundit readers. Corrected typo in "nominate."
