A new report from Know Your Rights Camp raises a disturbing possibility: that some officers have used license plate reader (ALPR) systems not to solve crimes, but to track the movements of partners or former partners. The details of the specific cases described are limited, but the underlying concern is one that deserves everyday people’s attention regardless of the particulars.
Why this is possible at all
ALPR networks like Flock Safety cameras capture the plate, location, time, and often a photo of every vehicle that passes, whether or not the driver is suspected of anything. That data is stored and made searchable, sometimes for weeks or months, and shared across agencies and even states. The system is built for convenience and speed, not for limiting who can look at what. Any officer with login access can, in theory, type in a plate number and pull up a timeline of everywhere that car has been photographed.
The gap between policy and practice
Most agencies that deploy ALPRs say searches must be tied to a legitimate investigation. But policies on paper only work if they are enforced. Audit logs exist to record who searched what and why, yet those logs are frequently reviewed only after a complaint surfaces, if at all. That reactive model means misuse, including using police tools to monitor an ex-partner, can go undetected unless someone notices and speaks up.
Why this matters beyond one report
Domestic violence advocates have long warned that abusers who also happen to be law enforcement officers have unique access to tools ordinary stalkers don’t. A patrol car, a badge, and a login to a plate reader database can turn a public safety system into a private surveillance tool. Even a small number of such cases undermines public trust in every camera on the map.
What communities can do
Residents don’t have to take an agency’s word that its ALPR program is being used properly. You can ask your local police department or city council how often audit logs are reviewed, who has access, and whether misuse has ever been found. You can find nearby ALPR cameras on our map, learn how these systems work on our learn page, and find concrete steps for pushing for oversight on our take action page. Transparency and independent audits, not just internal policy, are what keep a surveillance tool from becoming a weapon.
