Found in a brief filed in federal court:
See generally United States v. Dorosan, No. 08-042 (E.D. La. 2008)(U.S. Magistrate Judge's June 30, 2008 memorandum holding that Heller and Emerson hold that the Second Amendment protects a fundamental right)(Found on internet at www.volokh.com, scroll to July 16, 2008 blog entries and the entry entitled "Ninth Circuit's Sensible Response to a DC v. Heller Claim." At the end of the entry, click the seventh entry entitled "Another Early Post-Heller Second Amendment Case" and it will carry the HTML link to the Dorosan opinion).
I don't know what browser or what settings the lawyer was using, but generally just clicking on the link to the opinion will show the address ("http://volokh.com/files/dorosan.pdf") in the navigation bar — and, if it doesn't, right-clicking on the link will usually give you a way of getting the opinion. Plus, I'm told you can always do things the old-fashioned way, and attach a copy of the unpublished opinion to the brief.
But on the other hand, I like the idea of our site being a special library in which precious documents can be found, even if only through elaborate instructions passed along by the cognoscenti. Just go to the third floor, turn right at the first black set of stacks, go ten feet down, and open the seventh book on the bottom shelf — you can't miss it.
