Will these drones 'revolutionize' 911 response? L.A. suburb will be first to test

A black-and-white drone about the size of a sofa cushion took off with a gentle whir at the Hawthorne Police Department earlier this month, hovering and darting back and forth a few times before landing on a podium to a round of applause. A small audience and local TV news crews had gathered to see the unveiling of "Responder," marketed as the first drone built specifically to respond to 911 calls by quickly arriving at scenes, beaming a live video feed and, if necessary, dropping off medical supplies. The company behind the new drone, Seattle-based Brinc -- a tech startup with a 24-year-old chief executive -- has boasted it will "revolutionize the public safety landscape." But law enforcement agencies across Southern California and the country already employ drones for a variety of purposes, including 911 response, and skeptics warn about the risk of "mission creep" when the technology is weaponized or used for surveillance. Some Los Angeles activists have fought to limit police drone use, but Hawthorne's adoption of Brinc's Responder is a sign some local authorities are continuing to embrace unmanned aerial vehicles despite the pushback and price tag.
