Facial-recognition leads in criminal investigations
Detroit restricted facial-recognition investigations after Robert Williams's wrongful arrest
Problem
Detroit police used facial recognition to generate investigative leads from images of unidentified suspects.
Approach
The department's facial-recognition request log began in 2017. A false match led to Robert Williams's wrongful arrest in January 2020, according to his lawyers. A June 2024 court-enforceable settlement required independent reliable evidence before a facial-recognition lead could support a photo lineup or arrest, additional training and an audit of earlier cases. Police retained the technology, and a deputy chief said the revised practices would prevent future misidentifications.
Results
Takeaway
A computer-generated lead passed into an identification and arrest process without sufficient independent corroboration. The settlement placed new requirements on the human investigation surrounding the match.
