New York To Restrict Gun Carrying After Supreme Court Ruling

A new law effective tomorrow will make it more difficult to carry firearms in public by establishing gun-free zones in places like churches, parks, theaters, and public transportation. To obtain a concealed carry permit, applicants must complete 16 hours of classroom training and two hours of live fire exercises. This measure was passed after the Supreme Court invalidated the state's previous concealed carry law.
