Chicago scraps gunshot detection system accused of racial bias

Community groups say ShotSpotter system sends police to Black and Latino neighborhoods for unnecessary and hostile encounters

Chicago will not renew its ShotSpotter contract and plans to stop using the controversial gunshot detection system later this year, Mayor Brandon Johnson's office announced on Tuesday.

The system, which relies on an artificial intelligence algorithm and network of microphones to identify gunshots, has been criticized for inaccuracy, racial bias and law enforcement misuse. An Associated Press investigation of the technology detailed how police and prosecutors used ShotSpotter data as evidence in charging a Chicago grandfather with murder before a judge dismissed the case due to insufficient evidence.
