the statistic: CNN (Eric Levenson, 26 July 2026) on a running tally kept by the Institute for Justice. Milwaukee officer Josue Ayala used Flock to locate his romantic partner 124 times and her ex 55 times and pleaded guilty; a detective who investigated him was himself arrested for tracking two people. Flock runs about 120,000 cameras for more than 5,000 agencies in 49 states.
