GAO: DHS lacks bias-risk policies for most public-surveillance technologies

GAO-25-107302, "Law Enforcement: DHS Could Better Address Bias Risk and Enhance Privacy Protections for Technologies Used in Public." Reviews DHS law enforcement components' use of 20+ detection and monitoring technologies (face recognition, ALPRs, drones, pole cameras). Finds DHS lacks required bias-risk-assessment policies for most of them, CBP/ICE/Secret Service policies "did not always address key privacy protections," and civil-rights review isn't consistently required.
