CHICAGO (AP) — Some Capitol Hill Democrats and civil rights advocates are concerned about how police and prosecutors increasingly use algorithm-powered technologies that may amplify racial bias. In response to an Associated Press investigation into the ShotSpotter gunshot detection system, Democratic Sen. Ron Wyden of Oregon says artificial intelligence-backed tools can “increase the potential for sending innocent people to prison.” Wyden says he and seven other Democrats are waiting for a U.S. Justice Department response to their demand for oversight of the millions in federal funds sent to law enforcement agencies to buy algorithm-powered technologies. Activists rallied in front of a Chicago police station on Thursday demanding the city end its contract with ShotSpotter.
