Police mass face recognition in the US will net innocent people

The findings suggest that about a quarter of all police departments in the US have access to face recognition technology. That police are using face recognition technology is not a problem in itself. In a world with a camera in every pocket, they would be daft not to. But face recognition can be used far more broadly than fingerprint recognition, which means it carries a higher risk of tagging innocent people. Fingerprints are difficult to work with.
