Facial recognition technology is known to have flaws. In 2019, a national study of over 100 facial recognition algorithms found that they did not work as well on Black and Asian faces. Two other Black men -- Robert Williams and Michael Oliver, both of whom live in the Detroit, Mich., area -- were also arrested for crimes they did not commit based on bad facial recognition matches. Like Mr. Parks, Mr. Oliver filed a lawsuit against the city over the wrongful arrest. Nathan Freed Wessler, an attorney with the American Civil Liberties Union who believes that police should stop using face recognition technology, said the three cases demonstrate "how this technology disproportionately harms the Black community."
