Flock, a private firm, has rapidly expanded its AI licence plate reader network across the United States.

At over 130000 units nationwide, the system is predominantly used by law‑enforcement agencies to track vehicles.

While proponents argue it aids public safety, critics warn the mass surveillance of private vehicles raises serious privacy and civil‑rights concerns.

Protests and legal challenges have emerged in several states, and the BBC’s Verify team has begun a deeper look at how Flock’s data practices stack up against legal standards.

Reporter Jake Horton covered the story for BBC Verify and said the network’s growth has prompted a wave of scrutiny.
