NoCams Muskego Lawsuit: Waukesha County Flock Camera Warrant Challenged

• Civic group NoCams Muskego, along with other plaintiffs, has sued Waukesha County and 11 municipalities over their use of Flock cameras.
• The lawsuit alleges that police officers' warrantless access to the Flock database for vehicle tracking violates Fourth Amendment privacy rights.
• Over 120 Flock cameras in Waukesha County jurisdictions record vehicle movements and upload data to an AI-powered, searchable database.
• Plaintiffs cite the Supreme Court's *Chatrie v. United States* ruling, arguing that pervasive vehicle tracking requires a warrant.
• Flock Safety plans to implement a mandatory audit tool for law enforcement users starting January 1 to address concerns about misuse.

This legal challenge aims to establish that the pervasive vehicle tracking enabled by Flock cameras constitutes a Fourth Amendment search, necessitating a warrant.

A significant legal challenge has been launched in Wisconsin, directly confronting the widespread deployment and use of Flock camera technology by local governmental bodies. The civic advocacy group NoCams Muskego, alongside Citizens Defending Liberty and Waukesha County resident Donavan Haidinger, has initiated a lawsuit against Waukesha County and eleven of its constituent municipalities. The complaint, filed recently, asserts that the current implementation of Flock cameras and the associated database access by law enforcement infringes upon citizens' Fourth Amendment rights, specifically challenging the warrantless use of Flock camera data.

The plaintiffs contend that police officers in these jurisdictions are permitted to search the Flock database for vehicle movements—past, present, and even potential future—without first obtaining a warrant. This practice, they argue, facilitates a level of surveillance previously unimaginable, allowing for precise tracking of individuals' daily routines, from grocery runs to attending church, work, or even political activities like voting or protesting. The lawsuit specifically names the cities of Muskego, Oconomow, New Berlin, Waukesha, Delafield, and Brookfield, alongside the villages of Mukwonago, Hartland, Menomonee Falls, Elm Grove, and Pewaukee, as defendants.

Across these Waukesha County jurisdictions, more than 120 Flock cameras have been installed. These devices are strategically placed to record vehicle data, and the plaintiffs highlight that none of the defendant entities currently mandate a warrant for law enforcement to access the extensive Flock location database. This lack of a warrant requirement forms the crux of the legal challenge, aiming to safeguard privacy rights against pervasive vehicle tracking.

Flock Safety, the company at the center of this dispute, provides surveillance technology that includes solar-powered cameras and cloud-based software. These cameras are typically mounted in public spaces such as highways, intersections, and parking lots. Their primary function is to capture images of all passing vehicles and their license plates, which are then uploaded to a centralized, searchable database. This system leverages artificial intelligence to process the data, creating what the company markets as a “vehicle fingerprint.”

The resulting database is accessible to various Flock customers, including law enforcement agencies, local governments, and even private entities like homeowners’ associations. Police departments within the defendant municipalities, according to the lawsuit, are authorized to query this database and utilize other Flock tools without needing a warrant or demonstrating probable cause. The plaintiffs emphasize that these cameras record movements near sensitive locations, including private residences, gun stores, home improvement centers, and polling places within the Waukesha area.

The lawsuit underscores that the ability for any Flock customer, including police, to query this extensive database in multiple ways, coupled with the absence of a warrant requirement from the defendant municipalities, creates a system ripe for potential privacy infringements. The data collected and stored allows for detailed monitoring of individuals' movements, raising significant concerns about the scope of government surveillance.

At the heart of the NoCams Muskego Flock camera warrant lawsuit is the assertion that the warrantless use of this technology directly contravenes the Fourth Amendment of the U.S. Constitution. The plaintiffs argue that citizens retain a reasonable expectation of privacy even when traveling on public roads, and that the continuous, precise tracking of their movements by a police license plate reader network constitutes a search requiring judicial oversight. They contend that the Flock Safety database warrant requirement is essential to uphold these constitutional protections.

This legal challenge aims to establish that the pervasive vehicle tracking enabled by Flock cameras constitutes a Fourth Amendment search, necessitating a warrant. To bolster their claim, the plaintiffs point to established U.S. Supreme Court precedent. Specifically, they reference *Chatrie v. United States*, a case where the high court determined that obtaining an individual’s Google location history generally constitutes a Fourth Amendment search, thereby requiring a warrant or a recognized exception. The lawsuit posits that despite the relative novelty and rapid proliferation of Flock camera technology, it should not be exempt from the same constitutional standards applied to other forms of digital location tracking.

The complaint highlights that while some of the defendant municipalities' policies stipulate that the Flock program should only be used for legitimate law enforcement business, this provision does not address the fundamental issue of warrantless access. The plaintiffs seek a court order that would compel law enforcement to secure a warrant before accessing the Flock location database, thereby establishing a critical safeguard against what they view as an unconstitutional invasion of privacy through pervasive vehicle surveillance.

While the lawsuit underscores significant privacy concerns, law enforcement agencies often champion Flock camera technology as a vital asset in combating crime. Police credit these systems with successfully locating missing persons and tracking suspects involved in violent crimes, portraying them as an important crime-fighting invention. However, this perspective often clashes with growing public backlash regarding privacy implications and documented instances of alleged law enforcement abuse. Such concerns have prompted several cities nationwide to dismantle their Flock camera installations.

In response to the increasing scrutiny and privacy debates surrounding the Flock Safety database warrant requirement, the company's CEO, Garrett Langley, announced upcoming product enhancements. Effective January 1, law enforcement customers will be mandated to implement an audit tool designed to detect and flag abnormal search behavior within the system. Should this tool identify suspicious activity, the user account will be temporarily locked, pending a thorough review.

This proactive measure by Flock Safety aims to address a key concern articulated in the recent complaint: the potential for police officers to misuse the technology for personal reasons. The implementation of mandatory guardrails and auditing capabilities represents an attempt by the company to mitigate privacy risks and ensure responsible use of its powerful vehicle tracking capabilities, even as the legal challenge in Waukesha County seeks to impose a judicial warrant requirement.

This lawsuit challenges the warrantless use of Flock camera data, potentially establishing a precedent for Fourth Amendment protections against pervasive vehicle surveillance. Lawyers advising law enforcement or municipalities using such technology should monitor this case for evolving warrant requirements and privacy compliance obligations.
