A month after a mass shooting of school children rocked the nation, gun rights advocates scored their first U.S. Supreme Court victory in more than a decade when a divided court on Thursday struck down New York’s limit on who can carry a concealed gun outside of the home for self-defense.

The 6-3 conservative majority, led by Justice Clarence Thomas, said the Second Amendment was violated by New York’s 108-year-old requirement that those seeking a concealed carry license must show a “proper cause” for it, a special need to defend themselves.
