That’s right. Face recognition use by police in the United States is very, very common. Over half of all American adults are in a database that’s used for criminal investigations, thanks to getting a driver’s license. Robert Williams was not identified through a former mugshot; he was identified through his driver’s license, which most of us have. In addition, we estimate conservatively that over a quarter of all 18,000 law enforcement agencies across the country have access to use face recognition. The most concerning feature is that there are few if any rules governing how this technology can or, more importantly, cannot be used.
