From The Truth About Guns:

In his opinion, New York Rifle & Pistol Association v. City of New York is just such a case. Last week, the plaintiffs filed a brief in support of their petition for writ of certiorari. The complaint involves  the City of New York’s law that prevents gun owners from transporting licensed, locked and unloaded firearms outside the city under any circumstances. They can only use their guns within the five boroughs.
