The Heller case currently before the Supreme Court will conceivably be one of the most important decisions in the last twenty-five years. In well-written non-legalese,Glenn Reynolds and Brannon Denning have provided a great breakdown on the legal dynamics surrounding the case

Arguably, gun-rights supporters have much more at stake in Heller than their opponents.  The Court’s adoption of the individual-rights reading may be little more than symbolic; if not, it may take years before the Court deigns to clarify its decision.  But a rejection of their position would virtually repeal the Amendment, perhaps emboldening gun-control proponents whose initia­tives were often stymied by legislators’ invocation of the Second Amendment.  On the other hand, a loss might galvanize political action, as losses in Kelo and Bowers v. Hardwick did for property-rights and gay-rights activists.
