Flock's New Audit Tool Faces Scrutiny Over Efficacy
Flock, a prominent surveillance technology startup, recently unveiled a suite of new policies and tools aimed at enhancing accountability and curbing misuse within its automated license plate reader (ALPR) camera systems. The announcement, made on Thursday, introduces measures designed to provide law enforcement customers with clearer operational guidelines, though a key tool's internal workings remain largely opaque, drawing skepticism from privacy advocates.
Flock's New Policies Target Data Management and Misuse

The company's latest initiatives include significant adjustments to data retention and sharing protocols. Flock is now recommending that police departments reduce their data retention period from 30 days to just seven days. This change is complemented by the introduction of "Evidence Mode," an option for customers to retain data for longer periods in "exceptional cases," which necessitates a specific case number for activation.
Furthermore, customers will gain the ability to impose limits on data shared with other customers, a restriction based on the specific type of offense under investigation. This move aims to provide greater granular control over sensitive information, potentially reducing unauthorized access or scope creep in investigations.
Audit Assistance Becomes Mandatory for Enhanced Accountability
Central to Flock's new strategy is its "Audit Assistance" tool, initially launched in April. The startup has now mandated that all its customers enable this feature by the end of the year, citing its importance in identifying and mitigating system abuse. According to Flock, the tool is designed to "detects abnormal activity and flags it for Administrator review." Should atypical activity be identified, the system can automatically lock out flagged users until an administrator intervenes, a measure intended to provide immediate compliance security.
Flock states that Audit Assistance has already proven effective in helping customers identify and stop misuse. Several executives have publicly endorsed the tool's capabilities. Ashley Haber, Flock's head of trust and compliance, mentioned in a video that the tool can flag "what may look like an odd search history from a specific user," offering insights into user behavior. Similarly, Flock co-founder Paige Todd highlighted its ability to flag "unusual patterns early," citing an example of a user "searching the same plate repetitively for more than 30 days." Major Patrick Krieg of the Dunwoody, Georgia Police Department, a Flock customer, also lauded the feature in a press release, describing it as "an algorithm that has notified us of any type of bias."
The Bibb County Sheriff's Office specifically credited Audit Assistance with uncovering the recent misuse of Flock cameras by former deputies, underscoring its potential in real-world accountability scenarios.
Understanding the Mechanics of Flock's Audit Assistance
Despite the company's strong emphasis on Audit Assistance and its purported benefits, a significant gap remains in the public's understanding of how the tool actually functions. Flock describes the feature as one that can "surface atypical activity early and review it quickly with a clear, documented workflow." However, the exact operational details of this "algorithm" remain undisclosed.
TechCrunch, a technology news outlet, has raised pertinent questions regarding the tool's underlying technology, including how the algorithm works, the nature of the data it is trained on, and whether it employs a large language model or other forms of artificial intelligence. Further inquiries sought to clarify the specific patterns it is designed to surface and what exactly triggers a flag as "abnormal activity."
Flock has clarified to TechCrunch that Audit Assistance is not based on Machine Learning (ML) or Artificial Intelligence (AI). Instead, the company stated, "It is a data tool that flags atypical search patterns for further review." An illustrative example provided by Flock for triggering a flag would be a user searching for the same license plate using multiple different case codes, which "could potentially indicate abuse." The company emphasizes that a flag does not definitively confirm abuse but rather "warrants further investigation."
Privacy Experts Demand Greater Transparency and Independent Audits
The lack of detailed technical information about Audit Assistance has fueled skepticism among privacy experts and critics of surveillance technology. Numerous questions regarding the tool's effectiveness, such as its false positive and false negative rates, and whether it has undergone any independent third-party audits, remain unanswered.
Chad Marlow, senior policy counsel at the American Civil Liberties Union (ACLU), expressed significant reservations in response to Flock's announcement. He stated that "there is no evidence that the tool works consistently" to address abuse. Marlow criticized Flock's claim that recent arrests of officers for misuse serve as proof of the auditing tool's efficacy, arguing, "Unless we know the number of officers misusing the system, we cannot conclude if Flock and its auditing tools are catching 95% of violators or 5%." He strongly advocated for an independent evaluation of the tool's actual effectiveness, suggesting that without such an audit, it could be mere "window dressing" rather than a genuine security measure.
Cooper Quintin, a security researcher and senior public interest technologist at the Electronic Frontier Foundation (EFF), cast doubt on the tool's overall impact, suggesting that even if it works, "law enforcement will figure out ways to get around it." Quintin stressed that the ultimate measure of accountability lies in the consequences for abusers. He cautioned that if the tool reports to the same police agency engaged in abuse, it merely serves as "a fig leaf for Flock," advocating for legislative action that constrains technology use and requires warrants.
While acknowledging that making Audit Assistance mandatory is a positive step, Rachel Levinson-Waldman, director of the Brennan Center's Liberty and National Security Program, told TechCrunch that "in theory" the tool is "a great idea." However, she echoed the call for the tool itself to "be audited," citing insufficient information about its practical application and effectiveness.
Context of Abuse and Calls for Accountability
Flock's recent announcements follow years of documented incidents involving the misuse of its technology by customers. Just earlier this week, three former Georgia sheriff's deputies were arrested and charged with using Flock cameras to stalk individuals with whom they had "personal relationship at the time," as detailed by the Bibb County Sheriff's Office. In this specific case, Bibb County Sheriff David Davis directly attributed the uncovering of this misuse to Flock's new Audit Assistance tool.
The ongoing dialogue between technology providers, law enforcement, and civil liberties advocates highlights the critical need for robust compliance security and transparent operating margins in the deployment of surveillance technologies. As ALPR systems become more pervasive, ensuring clear oversight, measurable effectiveness, and genuine accountability remains a paramount concern for maintaining public trust and safeguarding individual privacy.
