With more sharks along the beach, police are using these drones to protect swimmers

This summer, Long Island saw 5 shark attacks in just 24 hours. As more sharks come closer to the shore, New York State Park Police are deploying a trove of drones to help spot sharks before they get close to swimmers. CNN's Clare Duffy got a hands-on demonstration of how the technology works. Produced by John General, Deborah Brunswick and FJ Feng
