Few Rules Govern Police Use of Facial-Recognition Technology

They call Amazon the everything store--and Tuesday, the world learned about one of its lesser-known but provocative products. Police departments pay the company to use facial-recognition technology Amazon says can "identify persons of interest against a collection of millions of faces in real-time." More than two dozen nonprofits wrote to Amazon CEO Jeff Bezos to ask that he stop selling the technology to police, after the ACLU of Northern California revealed documents to shine light on the sales. The letter argues that the technology will inevitably be misused, accusing the company of providing "a powerful surveillance system readily available to violate rights and target communities of color." The revelation highlights a key question: What laws or regulations govern police use of the facial-recognition technology?
