The supervisors voted 8-to-3 in favor of making it a new policy despite opposition by civil rights groups, but now they seem to have had a change of heart.During the second of two required votes before a policy can be sent to the mayor's office for final approval, the board voted 8-to-3 to explicitly ban the use of lethal force by police robots.Authorities could only use the robots for lethal force after they've exhausted all other possibilities, and a high-ranking official would have to approve their deployment.Dean Preston, one of the supervisors who oppose the use of robots as a deadly force option, said the policy will "place Black and brown people in disproportionate danger of harm or death."We should be working on ways to decrease the use of force by local law enforcement, not giving them new tools to kill people.""
