VentureBeat reports that police in Chula Vista, California are successfully using drones to witness and record crimes as they happen. The police department launched the partnership with Cape last year, and since October, the two remotely piloted drones have reportedly "assisted in 21 arrests, spanning 249 flights over the course of 81 flight hours." The report specifically mentions a case where a woman allegedly tried to run over a man on an (allegedly) stolen bike, and that the drone's observation of events will be used in court even though no police officers were physically there to witness the crimes. Fire departments are reportedly interested in the drones as well, and it sounds like the trials will expand to other areas sometime soon. Check out the department's announcement video here. Other participants in San Diego, the largest city in the country participating in the program that required a regional government sponsor, include UC San Diego Health to deliver blood and medical supplies, Uber Eats for food deliveries, and AT&T to test 5G networks. The first responder concept means drones are not deployed after a crime occurs, but proactively deployed for a large number of scenarios. In almost all instances, Sallee said, the drones gets there before officers in vehicles on the ground. The pilot program is currently limited to a one-mile radius around headquarters in downtown Chula Vista, the area of the city most likely to make 911 calls for police.
