Boston City Councilors voted unanimously to ban the use of facial-recognition technology by police -- technology the Boston Police Department currently doesn't use anyway due to its unreliability. All 13 councilors voted in favor of the order authored by Councilors Ricardo Arroyo and Michelle Wu to ban the city from using technology that matches people's faces. Mayor Marty Walsh's office said the mayor would review the legislation, not committing to whether he'd sign it or not. "It puts Bostonians at risk for misidentification," Arroyo said. A recent MIT study found that the technology was wrong more often when trying to identify darker-skinned people.
