The City of San Francisco became the first city in the United States to ban law enforcement, as well as other city agencies, from using facial recognition technologies when its Board of Supervisors on Tuesday approved the Stop Secret Surveillance Ordinance.

Aaron Peskin, a member of San Francisco’s Board of Supervisors, has proposed a ban on the city’s agencies from using facial recognition technology. If the ordinance, offered by Peskin on Tuesday, succeeds, San Francisco would be the first U.S. city to ban facial recognition technology.
