In one paragraph

Montana's SB 397 (Chapter 781 of 2023), the Facial Recognition for Government Use Act, bars state and local agencies, law enforcement, public employees and officials from using continuous facial surveillance and, with exceptions, from obtaining or using facial recognition technology or contracting vendors for it. The Department of Justice and local police may use it in criminal investigations under restrictions, including a warrant requirement, must tell defendants before trial, and must report use annually. Agencies may use facial verification only under a written use and privacy policy, with notice, vendor retention limits and human review training. People harmed may sue.
