From Texas Standard:
Ever since two important cases struck down gun restrictions in Washington, D.C. and Chicago – rulings that essentially protected gun ownership in the home – a question has remained as to whether it's legal to carry guns in public. But now, the Supreme Court is planning to review a case dealing with that very question; it's known by the shorthand "New York State Rifle."
Adam Winkler is a professor at UCLA School of Law who specializes in American constitutional law and the Supreme Court. Winkler says the case challenges a New York City ordinance that limits where people with permitted guns can bring them into public; they can bring them to specified gun ranges, for example.
