San Francisco Police Department's License Plate Data Misuse Raises Legal Concerns

Overview of the Incident
The San Francisco Police Department (SFPD) has come under scrutiny for allowing out-of-state law enforcement agencies to conduct over 1.6 million searches of its license-plate reader (LPR) data, potentially violating California's sanctuary laws. These laws prohibit police from assisting in immigration enforcement and restrict sharing data from automated license-plate readers with out-of-state agencies. The searches reportedly included at least 19 instances linked to U.S. Immigration and Customs Enforcement (ICE).
Details of the Data Sharing
The controversial LPR technology, provided by Atlanta-based Flock Safety, captures and stores information about every vehicle passing through its 400 cameras installed across San Francisco. Reports indicate that between August 2024 and February 2025, the SFPD granted direct access to its LPR data to numerous out-of-state agencies, enabling a significant volume of searches without explicit approval. The SFPD has since cut off access to these agencies as of February 11, 2025.
Official Responses and Accountability Measures
In response to the revelations, the SFPD has committed to launching a transparency portal to disclose which agencies have access to its LPR data. The department stated that it is conducting routine audits to ensure unauthorized users are not querying its system. However, the SFPD did not address specific inquiries regarding the ICE-related searches.
California Attorney General Rob Bonta and City Attorney David Chiu have been urged by privacy advocates to hold the SFPD accountable for these violations. Bonta's office has emphasized its ongoing engagement with local law enforcement, reiterating that sharing license-plate data with out-of-state agencies is prohibited.
Criticism from Privacy Advocates
Privacy advocates have expressed significant concern over the SFPD's actions. Brian Hofer, executive director of Secure Justice, criticized the department's handling of sensitive data, stating, “There’s always been this ‘trust us’ position from law enforcement... But when you see these numbers of violations... it calls all of that into question.” Supervisor Jackie Fielder has called for the Police Commission and Mayor Lurie to establish penalties for unauthorized sharing of LPR data for immigration enforcement purposes.
Conflicting Reports & Gaps
While the SFPD has claimed that out-of-state agencies no longer have access to its LPR data, the specifics of how many searches resulted in actionable intelligence remain unclear. Additionally, the nature of the searches conducted by agencies like the Franklin County Sheriff's Office in Georgia, which appeared to focus on immigration enforcement, raises questions about the intent behind these queries.
