Law enforcement may use facial recognition services provided by commercial and nonprofit entities to help solve crimes. For example, these services allow users to quickly search through billions of photos to help identify an unknown suspect in a crime scene photo. GAO was asked to review federal law enforcement’s use of facial recognition technology. This report examines, among other issues, the extent to which selected DHS and DOJ law enforcement agencies used facial recognition services to support criminal investigations; required staff to take training on facial recognition technology to use such services; and developed policies and guidance specific to facial recognition technology to help protect civil rights and civil liberties. GAO selected seven law enforcement agencies within DHS and DOJ based on various factors, including the number of facial recognition technology systems used. GAO reviewed documents, such as training requirements and policies for using facial recognition services. GAO also analyzed training records and interviewed agency officials. What GAO Recommends GAO is making 10 recommendations, including that FBI implement a training requirement and clarify the status of its training requirement to stakeholders. GAO also recommends that DOJ develop a plan to issue a facial recognition technology policy addressing safeguards for civil rights and civil liberties. Agencies concurred with all 10 recommendations.
