San Jose ALPR Surveillance Faces Scrutiny Over Privacy and Immigration Concerns

San Jose’s employ of automated license plate readers (ALPRs) is under increasing scrutiny from civil liberties groups and local communities concerned about privacy violations and potential misuse for immigration enforcement. A lawsuit has been filed challenging the San Jose Police Department’s practice of warrantless searches of ALPR data, although calls grow for the city to join other Bay Area localities in reconsidering or terminating their ALPR programs.

What are Automated License Plate Readers?

Automated license plate readers (ALPRs) are high-speed, computer-controlled cameras that automatically capture images of license plates and record the location and time of each scan. This data is then stored in databases, creating a detailed record of vehicle movements. Proponents argue ALPRs enhance public safety by aiding in the investigation of crimes, but critics contend they represent a form of mass surveillance with significant potential for abuse.

Growing Concerns About Data Access and Usage

Concerns center around who has access to the collected data and how it’s being used. While California law prohibits local police from sharing ALPR data with out-of-state or federal agencies, past instances reveal potential breaches of these regulations. As recently as 2023, at least 75 California police agencies were sharing ALPR records out-of-state . In 2024, San Francisco police allowed access to out-of-state agencies, with 19 searches specifically related to Immigration and Customs Enforcement (ICE) .

Even without direct access, federal law enforcement can request local police to conduct searches on their behalf. Investigations have revealed over 4,000 instances of police searches conducted for federal agencies, including immigration investigations .

Warrantless Searches in San Jose

A key point of contention in San Jose is the lack of a warrant requirement for accessing ALPR data. The San Jose Police Department is not required to demonstrate any suspicion of wrongdoing before searching the ALPR database, which contains a year’s worth of data representing hundreds of millions of records. In just over a year, San Jose police logged more than 261,000 ALPR searches – nearly 700 searches per day – without a warrant .

Legal Challenge and Community Response

The Services, Immigrant Rights and Education Network (SIREN) and the Council on American-Islamic Relations – California (CAIR-CA), represented by the Electronic Frontier Foundation (EFF) and the ACLU of Northern California, have filed a lawsuit challenging this practice of warrantless searches .

Several other Bay Area cities are also reevaluating their ALPR programs. Mountain View recently deactivated its Flock cameras after revelations of unauthorized access to the network. Los Altos Hills and Santa Cruz have terminated their contracts with Flock Safety due to concerns about ICE access, and East Palo Alto and Santa Clara County are currently reconsidering their participation .

Alameda County Establishes ICE-Free Zones

Demonstrating a commitment to protecting immigrant communities, Alameda County recently voted unanimously to establish “ICE-Free Zones,” prohibiting the use of county-owned property for U.S. Immigration and Customs Enforcement activities and . CAIR-SFBA applauded the decision, urging other jurisdictions to follow suit.

The Path Forward for San Jose

Critics argue that the risks associated with ALPR technology outweigh the benefits, particularly for vulnerable populations. They advocate for San Jose to join the growing number of cities and counties that are either limiting or eliminating their ALPR programs. Each day the cameras remain active, they collect sensitive location data that could be misused, jeopardizing the privacy and safety of residents. City leaders face increasing pressure to act decisively to protect community trust and fundamental freedoms.
