Word just in that the U.S. Supreme Court has granted certiorari in (i.e., decided to hear) the McDonald v. Chicago case discussed here previously - and, most importantly, did not appear to have limited the arguments to due process, as Chicago had suggested.
Specifically, here's how the issue is framed in today's order (scroll down to Docket No. 08-1521): "Whether the Second Amendment is incorporated into the Due Process Clause or the Privileges or Immunities Clause of the Fourteenth Amendment so as to be applicable to the States, thereby invalidating ordinances prohibiting possession of handguns in the home."
Please forgive the momentary gloat, but this is precisely the question raised (which my thesis answers in the affirmative) in my 2007 Missouri Law Review article, entitled (in language virtually identical to the Court's stated issue): "Second Amendment Incorporation Through the Fourteenth Amendment Privileges or Immunities and Due Process Clauses."
So, the Privileges or Immunities argument we've been pushing, for so long, is ON in the Supreme Court. This is huge.
