The city of San Francisco approved an ordinance on Tuesday barring the police department and other city agencies from using facial recognition technology on residents. It's the first such ban of the technology in the country.
The ordinance, which passed by a vote of 8 to 1, also creates a process for the police department to disclose what surveillance technology they use, such as license plate readers and cell-site simulators that can track residents' movements over time. But it singles out facial recognition as too harmful to residents' civil liberties to even consider using.
