A Las Vegas shooting from a high-rise hotel that killed dozens of people in a packed concert below on Sunday, Oct. 1, 2017, has forced other cities to examine their tactics for dealing with this kind of nightmare scenario. In New York, which hosts Times Square New Year’s Eve and other events surrounded by high-rises, police say they use rooftop snipers to scan for threats, and make security sweeps of nearby hotels.
