Sanders Proposes Bill to Ban Federal Government Use of Flock License Plate Recognition Systems

Overview

U.S. Senator Bernie Sanders has introduced new legislation that would prohibit the federal government from using Flock Safety's automated license plate recognition technology. Based on available information, the bill's scope extends beyond Flock as a single vendor — it would cover all types of Automated License Plate Readers (ALPR).

This development reflects ongoing concern in U.S. political circles about large-scale surveillance technology, particularly as law enforcement agencies increasingly partner with private tech companies.

What Are Automated License Plate Readers?

Automated License Plate Readers are surveillance tools that combine cameras with computer vision technology. They capture license plate information from passing vehicles in real time and cross-reference it against databases, with applications ranging from traffic enforcement and parking management to criminal investigations.

Flock Safety is one of the most prominent vendors in this space, with its products deployed across numerous U.S. cities and communities. The core controversy surrounding these systems is that they can continuously and systematically record vehicle movement over extended periods — entirely without the vehicle owner's knowledge — accumulating vast repositories of location data.

From a technical standpoint, modern ALPR systems typically consist of high-speed cameras, infrared illumination modules, and edge computing units capable of identifying license plate characters with high accuracy even at highway speeds. The captured data is tagged with GPS coordinates and timestamps, then uploaded to cloud databases. Law enforcement agencies can query these databases to retrieve a specific vehicle's historical movement patterns and can even share data across agencies and jurisdictions. Flock Safety's business model incorporates cameras deployed in private residential communities and commercial parks, meaning data sources extend well beyond public roads — privately deployed devices also contribute location data to the broader network, significantly expanding the actual geographic scope of surveillance.

Core Legislative Goals

Based on currently available information, the key thrust of Sanders' proposal is to restrict federal-level procurement and use of this category of technology. By extending the bill's scope to cover all ALPR systems — not just one company — the legislative intent is clearly to draw boundaries around an entire class of surveillance technology rather than target a single vendor.

This type of legislation typically centers on several key concerns:

• Privacy rights: Vehicle location data can be used to reconstruct an individual's daily activity patterns, potentially implicating Fourth Amendment protections against unreasonable searches.
• Data retention and misuse risks: Long-term storage of massive datasets, if left unregulated, could enable secondary use or unauthorized sharing.
• Indiscriminate surveillance: ALPR systems record every vehicle that passes by without distinction — not just suspected targets — effectively creating a system of blanket surveillance.

The Fourth Amendment prohibits the government from conducting "unreasonable searches and seizures," but its application in the age of digital surveillance has long been contested. The 2018 Supreme Court case Carpenter v. United States marked a pivotal turning point: the Court ruled that the government cannot obtain weeks' worth of a citizen's cell phone location records from a telecommunications carrier without a warrant, because sustained location tracking reveals an intimate portrait of a person's private life. Critics argue that ALPR systems are functionally analogous to cell phone location tracking — both systematically accumulate location data without the subject's knowledge — and should therefore receive the same constitutional protection. This judicial precedent provides important legal grounding for the current legislative push.

The Broader Landscape of Technology Regulation

Sanders' proposal is the latest episode in an ongoing legislative battle over surveillance technology. As visual recognition, artificial intelligence, and data analytics capabilities have rapidly advanced, law enforcement tools have become dramatically more powerful — yet the corresponding legal frameworks have consistently lagged behind technological development.

For the AI and tech industry, this type of legislation carries real practical implications. Vendors of surveillance products must navigate increasingly stringent compliance requirements, and deployment of these technologies could be curtailed by tightening policy environments. How to strike the right balance between public safety and civil privacy remains an unresolved question.

Conclusion

Given the limited information currently available, the bill's specific provisions, legislative timeline, and ultimate prospects for passage remain to be seen. But the signal it sends is clear: faced with rapidly expanding automated surveillance capabilities, lawmakers are attempting to reassert boundaries on government authority to deploy such technology. The broader debate over privacy and technology shows no signs of cooling down anytime soon.
