Stop Flock

TL;DR (Summary)

Flock Safety markets AI surveillance that goes far beyond reading license plates; color, bumper stickers, dents, and other features are used to build databases and identify movement patterns. These systems are spreading rapidly, often without oversight, and are accessible to police without a warrant. They raise serious privacy and legal concerns, and contribute to a nationwide trend toward mass surveillance.

While this and other systems like it claim to reduce crime, there is little evidence to support that claim - and significant risk of abuse. Real public safety comes from investing in communities, not stalking them.

What Are Flock Cameras?

Flock Safety markets its devices as "AI-powered precision policing technology" - far beyond basic license plate readers (ALPRs). The system uses AI to create a "Vehicle Fingerprint" - identifying cars not only by license plate, but also by color, make and model, roof racks, dents/damage, wheel type, and more. Even bumper sticker placement is analyzed. This lets law enforcement search for a "blue sedan with damage on the left side" even without a license plate.

But the surveillance goes deeper. Using a feature called "Convoy Analysis", the system can detect vehicles that frequently appear near each other - suggesting associations between drivers or accomplices. The platform can also flag vehicles that routinely travel to the same locations across time. Flock describes this as a way to "identify suspect vehicles traveling together" or "pinpoint associates."

The data is logged and made searchable across a nationwide law enforcement network - which officers in subscribing agencies can access without a warrant. According to Flock, the system can automatically flag a vehicle based on its history, route, or presence in multiple locations linked to a crime.

Privacy and Civil Liberties

While these tools may aid in locating stolen cars or missing persons, they also create a detailed record of everyone's movements, associations, and routines. That data has already been misused - like when a Kansas police chief used Flock cameras 228 times to stalk an ex-girlfriend and her new partner without cause.

The scope of this tracking becomes clear when you see real-world examples. In 2025, a journalist drove 300 miles across rural Virginia and was captured by nearly 50 surveillance cameras operated by 15 different law enforcement agencies. When he requested his own surveillance footage, he discovered the cameras had documented patterns that made his behavior "predictable to anyone looking at it."

Flock cameras and similar surveillance tools raise serious Fourth Amendment concerns by enabling broad, warrantless tracking of people's movements. In 2024, a trial court held that the Flock network functioned as a "dragnet over the entire city." The judge in the case equated it to placing GPS trackers on every vehicle - a practice that the U.S. Supreme Court has ruled requires a warrant.

Furthermore, Flock's data enables biased enforcement. In Oak Park, Illinois, 84% of drivers stopped using Flock camera alerts were Black - despite the town being only 21% Black. Mass surveillance isn’t just about policing; there are major business interests involved as Flock encourages private entities like businesses and HOAs to share their footage, broadening the surveillance net into private spaces.
