São Paulo AI facial recognition policing: 8% false arrest rate in first year stirs controversy
São Paulo introduced AI facial recognition in late 2024, integrating 40,000 cameras. In 2025 robberies fell 15% and nearly 2,900 fugitives were arrested, but the initial false positive rate exceeded 8%, leading to wrongful detentions including elderly people, patients, and people with expired warrants or civil debts, prompting privacy and over-policing concerns.
