Something big is brewing in San Jose—and it’s not about tech innovation this time. It’s about who’s watching whom.
Three local drivers have filed a class action suit against the city and its police department, arguing that the widespread use of AI-powered surveillance cameras crosses a constitutional line. Backed by the Institute for Justice, the case claims that constant tracking of vehicles amounts to an unreasonable search under the Fourth Amendment.
At the center of it all is Flock Safety, a company that has quietly built one of the most extensive license plate tracking networks in the country.
Tracking Every Turn
Here’s how it works. Cameras placed across the city scan and log license plates as cars pass by. Each sighting is tagged with time and location, then stored in a database that law enforcement can search.
Individually, these snapshots might seem harmless. But over time, they start to tell a story. Where you go, how often, and even patterns you didn’t realize you had.
In San Jose alone, these cameras recorded nearly 2.8 million vehicle sightings in just one month. That’s not occasional surveillance—that’s a near-constant digital trail.
Where It Starts to Feel Uncomfortable
The lawsuit leans heavily on one idea: this isn’t just about cars, it’s about people.
When you stitch together enough data points, it becomes surprisingly easy to map someone’s life. Visits to hospitals. Stops at legal offices. Attendance at protests or community meetings.
One of the plaintiffs says a camera sits right along his daily route, making it almost impossible to leave or return home without being logged. That kind of visibility, he argues, shouldn’t exist without a warrant.
There’s also a deeper concern what happens to this data later? Even if it’s used responsibly today, there’s no guarantee it won’t be misused tomorrow.
The City Tries to Course-Correct
To its credit, the city hasn’t ignored the backlash. Officials recently cut down how long this data can be stored—from a full year to just one month.
But for critics, that’s a surface-level fix. The core issue, they argue, isn’t just how long the data is kept—it’s that it’s being collected in the first place, at such scale, without direct oversight.
The lawsuit is asking for stricter safeguards, including requiring warrants to access the data or limiting how much of it can be stored at all.
Bigger Than One City
This isn’t just a San Jose problem. It’s part of a much larger conversation happening across the U.S.
Cities are increasingly turning to AI-driven tools to improve policing. And companies like Flock Safety argue their systems help solve crimes faster and more efficiently.
But here’s the tension at what cost?
This AI surveillance lawsuit could end up setting the tone for how far authorities can go in using technology to monitor everyday life. Because once surveillance becomes invisible and constant, it stops feeling like protection—and starts feeling like something else entirely.
