San Francisco has become the first major city in America, if not the world, to effectively ban, for now, facial recognition technology and other forms of state surveillance.

In an 8-1 vote on Tuesday, the city's Board of Supervisors passed a new ordinance that requires all local government departments – including the police – to follow a series of new policies and get explicit permission from the Board before introducing any new technology that stores information on individuals.
