Is the Second Amendment a Real Amendment?

It looks like we'll soon find out; the Supreme Court has accepted cert on McDonald v. Chicago, a gun rights case brought by Alan Gura, the lawyer who won the Heller case.  The court has been dodging the twin questions of whether the Second Amendment protects an individual right to bear arms, and whether it can be incorporated against the states, for decades.  It looks like the question will finally be settled--at least as much as Supreme Court decisions ever settle things--in the next year.
