Tom Goldstein Predicts:

McDonald v. City of Chicago, which presents the question whether the Second Amendment’s right to keep and bear arms is “incorporated” and therefore applies to state and local gun regulation. McDonald was argued in February, and the only Justice not to write from that sitting is Justice Alito. He therefore likely has the Court’s opinion.
Justice Alito was a member of the five-Justice majority that recognized a Second Amendment right outside the context of militia service in the Heller case. He therefore is a likely vote for finding incorporation. At oral argument in McDonald, Justice Alito seemed quite doubtful about the City’s efforts to suggest a narrow ground for ruling.
I predict that Justice Alito will write the Court’s opinion in McDonald recognizing that the Second Amendment is incorporated. But given Justice Alito’s sensitivity towards law enforcement, I doubt that the opinion will call into question a broad swath of firearms regulation.
