An EFF analysis of millions of searches of Flock Safety automated license plate reader (ALPR) logs finds widespread “mission creep”: police routinely use ALPR databases without warrants for low-level or noncriminal purposes. Agencies leasing or subscribing to Flock cameras collect license plates, vehicle details, timestamps and locations; many then share networks nationally, enabling frequent searches. Examples include school residency checks—Buford City Schools ran hundreds of searches labeled
Tech professionals should care because ALPR system design, data retention, and access controls affect user privacy, legal risk, and public trust. Understanding mission creep informs product choices, compliance obligations, and system hardening.

Residents in multiple U.S. cities have begun covering Flock Safety license-plate–reading surveillance cameras with black trash bags and other obstructions after privacy and civil-liberties concerns. Flock Safety, which sells automated license plate readers (ALPRs) to neighborhoods and law enforcement, has seen pushback as activists and locals argue the devices enable mass surveillance, racial profiling and opaque data-sharing with police. The protests matter because Flock’s networked cameras and their analytics are part of a growing private surveillance market that intersects policing, municipal procurement and public trust. The clashes highlight legal, regulatory and technical debates over deployment, transparency, retention policies and whether communities can limit or block such systems.
An EFF analysis of millions of searches of Flock Safety automated license plate reader (ALPR) records shows law enforcement agencies using the data far beyond targeted criminal probes, with no warrant requirement enabling widespread “mission creep.” Agencies routinely mine nationwide ALPR pools for low-level matters — from residency verification for school districts to background checks, noise complaints, and even targeting protesters, abortion seekers, immigrants and ethnic groups. Case data from Buford City Schools (GA) shows school police ran hundreds of ALPR searches marked as residency verification, sometimes querying plates across thousands of networks, exposing detailed location histories. The findings raise privacy and civil liberties concerns about unchecked surveillance, data sharing practices, and lack of legal safeguards.
An EFF analysis of millions of law enforcement searches of Flock Safety automated license plate reader (ALPR) data finds pervasive mission creep: agencies routinely use ALPRs beyond specific criminal investigations for low-level tasks like school residency checks, employment background checks, noise complaints, and targeting protesters or abortion seekers. The data shows wide sharing across networks—searches often query thousands of cameras nationwide—so a single residency verification can expose detailed movement histories. Buford City Schools (GA) logged hundreds of ALPR searches labeled for residency verification, illustrating how school districts enlist police to audit families’ movements. The pattern matters because absent warrant requirements, unrestricted access to sensitive location data enables broad surveillance and significant privacy harms.

Examples include school residency checks—Buford City Schools ran hundreds of searches labeled “residency verification”—as well as employment background checks, noise complaints, protests, abortion seekers and immigrant surveillance. The reporting underscores privacy harms from unrestricted access and broad data sharing, arguing that ALPRs have become general trackers of everyday movement rather than narrowly targeted investigative tools.
