The Supreme Court on Thursday struck down a New York law that regulated who is allowed to carry a concealed weapon in public, expanding gun rights nationwide.

In a 6-3 decision by the court's conservative majority, the justices ruled that requiring people to demonstrate a particular need for carrying a gun in order to get a license to carry one in public violated the Second Amendment right to “keep and bear arms.”

Justice Clarence Thomas wrote for the majority that the Constitution protects “an individual’s right to carry a handgun for self-defense outside the home.”

In a dissent joined by his liberal colleagues, Justice Stephen Breyer focused on the toll taken by gun violence. “Since the start of this year alone (2022), there have already been 277 reported mass shootings—an average of more than one per day,“ Breyer wrote.

The decision expected to ultimately allow more people to legally carry guns on the streets of the nation’s largest cities — including New York, Los Angeles and Boston — and elsewhere. About a quarter of the U.S. population lives in states expected to be affected by the ruling, the high court’s first major gun decision in more than a decade.
