License-plate reader firm Flock tightens rules amid backlash

Flock, which operates a nationwide network of AI-powered license-plate readers used by police, announced it will change officers' access to the system. The move follows growing backlash over mass surveillance and concerns about police misuse.

Why it matters: Flock's system shows how AI-powered surveillance tools scale far beyond their original use case once deployed nationally, and this change shows public and political pressure can force operational limits even without new legislation. It's a live case study for the broader debate over oversight of AI-driven policing tools like plate and facial recognition.
