When disarming the man in Los Angeles, the robot didn't negotiate. Instead, while the man was distracted, police used the robot to grab the man's weapon, which was on the floor behind him. The clearest precedent for this comes not from another bomb squad robot, but from a Customs and Border Protection Reaper drone, flown over a standoff near Grand Forks, North Dakota. In that case, cattle thieves holed up on a ranch with weapons to keep the police at bay. The Reaper, which can fly overhead for up to 24 hours at a time, used infrared cameras to watch the cattle thieves, and figured out when the armed men were asleep. The drone operator relayed that information to police, who then stormed the ranch and made arrests, without any shots fired.
