Senators Push for Tighter Rules on Flock’s Nationwide Surveillance Network

Senators expressed urgent calls on Wednesday for stricter regulations and enhanced privacy safeguards surrounding AI-powered license plate readers, as concerns mounted over the implications of unchecked access to vehicle-location data. This push unfolded during a Senate Judiciary Subcommittee on Crime and Counterterrorism hearing, which centered on Flock Safety, a surveillance network comprised of over 120,000 cameras spread across 49 states.

Flock advocates tout its interconnected system as a tool that facilitates the sharing of vehicle evidence among law-enforcement agencies, with search capabilities subject to audit controls. However, both lawmakers and witnesses expressed apprehension regarding the network's expanding scope, highlighting potential privacy infringements and Fourth Amendment rights.

Republican Senator Josh Hawley, who presides over the subcommittee, emphasized the need for clarity on what data surveillance firms accumulate, who can access it, how long information is retained, and how searches are executed. He also criticized the CEOs of Flock and other prominent surveillance companies for declining to appear before the committee. "Our Bill of Rights is still good no matter what the technology of the day is," Hawley asserted.

The concern extends beyond mere vehicle surveillance. Modern systems enable the searchability of extensive records across the network, potentially allowing investigators to piece together a comprehensive pattern of a person's life. Hawley cautioned that Flock's customers can construct detailed narratives of individuals' daily routines.

Ranking Member Dick Durbin, a Democrat, recognized the long-standing presence of license plate readers in law enforcement and acknowledged their legitimate uses in certain contexts. Nevertheless, he stressed the imperative for Congress to strike a balance between privacy and security.

Alasdair Whitney, legislative counsel for the Institute for Justice, highlighted how networked license plate readers have evolved from a point-in-time identification tool into a system capable of reconstructing a person's movements. He argued that the technology enables the government to "travel back in time" and reconstruct a person's past activities.

The Fourth Amendment, which protects against unreasonable searches and seizures, was invoked in the Supreme Court's 2018 decision in Carpenter v. United States. The court affirmed that the acquisition of historical cell-site location information constitutes a search under the Fourth Amendment, emphasizing that long-term location records can provide detailed insights into an individual's life.

Whitney urged Congress to mandate warrants before law enforcement searches historical location data and to impose limits on the retention period. He also proposed that federal funding should be contingent on states and localities adopting comparable safeguards. Sheriff Ross Teeple of Pinal County, Arizona, offered a distinct viewpoint from the law enforcement community.

He acknowledged the potential benefits of automated license plate readers in recovering stolen vehicles, locating missing persons, and responding to alerts. However, Teeple terminated his department's contract with Flock due to concerns regarding newer AI-powered systems and their potential constitutional implications. He questioned the distinction between physical tracking devices and AI-generated records of vehicle movements, questioning where the line should be drawn.

Testimony from Lindsey Isaacs, a Florida resident, underscored the real-world consequences of these surveillance technologies. Isaacs recounted how a Flock camera captured an image of her vehicle during a fatal-crash investigation, leading to her wrongful arrest for vehicular homicide. She spent 13 days in jail before prosecutors opted not to pursue charges.

Isaacs emphasized that technology does not exist in isolation, and information collected by such systems can significantly impact real human lives. Flock has responded to mounting scrutiny by adjusting its policies. The company now retains data for a maximum of seven days instead of 30, although retention periods may vary depending on customer agreements or local laws.

Flock also allows agencies to preserve specific information pertinent to active investigations through its Evidence Mode, and it ensures that every search is logged, access is controlled by local authorities, and user permissions are determined based on roles.
