In this Tuesday, May 2, 2017 photo, New York City police officers, including members of the Emergency Services Unit, walk down a cable on the Brooklyn Bridge during a training exercise in New York. The 400-team unit, an elite group of officers trained to handle the city’s most dangerous rescues, trains for months not only on technical rescue techniques, but also on how to talk to people to get them down safely.
