The Surveillance Advisory Board held a special meeting on July 24, 2025, in Vallejo, California, to discuss the effectiveness of the FLoC surveillance system during its beta testing phase. The meeting focused on the need for clear metrics to evaluate the system's performance and the police department's plans for its future use.

The discussion began with board members expressing concerns about the lack of data to assess the effectiveness of the FLoC system. It was noted that no comparative analysis had been conducted against previous data during the beta testing period. One board member emphasized the importance of having concrete metrics to determine whether the system had been successful, stating that anecdotal examples were insufficient for justifying its continuation.

The conversation shifted to the availability of criminal statistics used by the police department to evaluate various programs, including FLoC. Board members requested access to specific metrics that the department employs to measure program productivity. The police representatives acknowledged that they post a significant amount of statistical data on their website but did not provide clarity on the specific statistics relevant to the evaluation of the FLoC program.

As the meeting progressed, board members reiterated their desire for a comprehensive list of the metrics that would be used to assess the FLoC system's effectiveness. The lack of existing data and analysis raised questions about the police department's ability to justify the extension of the program beyond its beta testing phase.

In conclusion, the meeting highlighted the need for transparency and accountability in evaluating surveillance programs. Board members called for more detailed information from the police department to support any proposals for continuing the use of FLoC, emphasizing that informed decisions should be based on thorough analysis rather than limited examples. The board plans to follow up on these requests in future meetings to ensure that adequate metrics are established for evaluating the program's impact.
