A review by the Institute for Justice identified at least 16 documented cases across the United States in which police officers allegedly weaponized Flock Safety's automated license plate reader data to surveil romantic partners, ex-partners, and women they wished to pursue — the bulk of them occurring since 2024.
The cases span the country. In Milwaukee, Wisconsin, Officer Josue Ayala was charged with attempted misconduct in public office after prosecutors alleged he searched Flock readers nearly 180 times to track a woman he was dating and her former partner. In Sedgwick, Kansas, Police Chief Lee Nygaard resigned after allegedly using Flock cameras to track his ex-girlfriend more than 200 times. In Kechi, Kansas, Lieutenant Victor Heiar pleaded guilty to computer crime and stalking after using the system to monitor his estranged wife. In Riverside County, California, Deputy Alexander Vanny was convicted by a jury in December 2025 after using his department's Flock system to track his ex-fiancée's friend.
The oversight problem is as alarming as the abuse itself. Only a handful of these cases were initially discovered through internal police investigations. Most were uncovered through civilian complaints — meaning the systems Flock promotes as having internal safeguards failed to flag hundreds of abusive searches before harm was done.
