The New York City Police Department (NYPD) are copying signs declaring Times Squares gun-free status.
Robert Barrows, the NYPD's executive director of legal operations, held up one of the signs which reads "GUN FREE ZONE",at a City Council hearing on Tuesday focused on securing sensitive spaces after the Supreme Court gutted New York state's concealed carry handgun law, reports dpa news agency.
After the June ruling, state lawmakers passed and Governor Kathy Hochul signed laws prohibiting the carrying of concealed weapons in various high-risk settings including Times Square, subways, buses and bars.
The rules take effect Thursday.
City Council members also introduced their bill this month to redefine the Times Square area as a sensitive location after the ruling in New York State Rifle & Pistol Association v. Bruen.
Noting that more than 360,000 people pass through Times Square daily, Barrows said the state law and city bill "recognise that Times Square is a dense, complex and highly trafficked area".
He said the NYPD is working to educate cops and the public alike on developments since the conservative Supreme Court's ruling.
"The signage will be placed at every entry point in the zone," Barrows said. "This will be temporary. More permanent signage will be installed if, as expected, this bill becomes law."
He said sign installation will begin Thursday.
The placard also bears language saying that "Licensed gun carriers and others may not enter with a gun unless otherwise specially authorized by law" and warning that violation of the rule is a felony.
Before the Supreme Court ruling, which marked a historic expansion of federal gun rights into the public sphere and levelled a law that stood for more than a century, New Yorkers needed to show specific self-defence needs in order to acquire concealed carry handgun licenses.
The new state rules introduced after the decision make concealed carry a crime in sensitive places that include libraries, poll sites, schools and entertainment venues.
