But a recent attempt by the Jefferson Parish Sheriff’s Office to nab a high-end purse thief via facial recognition ended badly for a Georgia man who was jailed for almost a week over a false match, his lawyer says.A Baton Rouge Police Department detective then adopted JPSO’s identification of Reid to secure an arrest warrant alleging he was among three men involved in another luxury purse theft the same week at a shop on Jefferson Highway, court records show.The case highlights the pitfalls of a technology that more law enforcement agencies are adopting across the country, even as critics point to research showing bad matches at higher rates for some populations, including Black people and women.Lampert said last week that the technology is used by police only to develop suspects in cases where there are none, and that any match must be corroborated, like with a fingerprint.“It was always an assistance to law enforcement to establish probable cause.” That portrayal minimizes the technology’s expansive reach and potential for abuse in government hands, argued Chris Kaiser, advocacy director for the ACLU of Louisiana."
