San Francisco could become the first city in the nation to ban any city department from using facial recognition under a proposal that says any benefits of the technology outweigh its impact on civil rights, and Oakland may not be far behind.

In San Francisco, a Board of Supervisors committee is scheduled to vote Monday on the Stop Secret Surveillance Ordinance, which would make it illegal for any department to “obtain, retain, access or use” any face-recognition technology or information obtained from such technology.
