Taser developer Axon said this week it is working to build drones armed with the electric stunning weapons that could fly into schools and “help prevent the next Uvalde, Sandy Hook, or Columbine.” But its own group of technology advisers quickly panned the idea as a dangerous fantasy. The publicly traded company, which sells Tasers and police body cameras, floated the idea of a new police drone product last year to its artificial intelligence ethics board, a group of well-respected experts in technology, policing and privacy. Some of them expressed reservations. But they did not expect Axon’s Thursday announcement that it wants to send those Taser-equipped drones into classrooms.
