US lawmakers introduce bill to limit law enforcement's facial recognition use

U.S. Rep. Ted Lieu, D-Calif., and fellow House Democrats introduced a bill to regulate law enforcement's use of facial recognition technology. The bill would require a warrant stating there is probably cause an individual allegedly "committed a serious violent felony" before facial recognition can be used. "Our bill puts forth sensible guardrails that will protect the privacy of Americans against a flawed, unregulated and at-times discriminatory technology," Lieu said.
