Pittsburgh City Councilor Corey O'Connor introduced legislation this week that would regulate the city's purchase of facial recognition technology.O'Connor, who chairs council's public safety committee, said that while the city doesn't have any such systems, that this was a pre-emptive step to avoid racial profiling.Face recognition can misidentify people of color more frequently than white people, said the councillor. “We are just going proactive to say, 'If you're looking to get this in the future, come back to council and get it approved,'” O'Connor said, reported Wesa. “But it's been proven that it disproportionately harms certain people in this country.”
