Eight months pregnant, she was detained for 11 hours, questioned, and had her iPhone seized for evidence before being released. It's the latest in a string of false arrests due to use of facial-recognition technology, which many critics say is not reliable. The mistake seems particularly notable because the surveillance footage used to falsely identify Woodruff did not show a pregnant woman, and Woodruff was very visibly pregnant at the time of her arrest. The incident began with an automated facial recognition search by the Detroit Police Department.
