The Supreme Court just ruled in favor of striking down Washington D.C.'s gun ban.

The Court has released the opinion in District of Columbia v. Heller (07-290), on whether the District’s firearms regulations – which bar the possession of handguns and require shotguns and rifles to be kept disassembled or under trigger lock – violate the Second Amendment. The ruling below, which struck down the provisions in question, is affirmed.

Justice Scalia wrote the opinion. Justice Breyer dissented, joined by Justices Stevens, Souter and Ginsburg.

Before the ruling was issued this morning, the Obama campaign disavowed its "inartful" statement last year that "Obama believes the D.C. handgun law is constitutional."
