Judge calls Flock license plate scans indiscriminate mass surveillance

A federal judge ruled that a sheriff’s deputy violated a woman’s Fourth Amendment rights by using Flock to search for her license plate — without a warrant.

Flock is the network of cameras mounted on poles, streetlights, and traffic signals that quietly snaps every plate that passes. The system feeds data to law enforcement agencies across the country. It is not just a tool. It is a net.

The judge’s ruling matters because it targets the assumption that police can run a plate check whenever they want, no questions asked. In this case, the deputy did not have probable cause. No judge signed a warrant. No court approved the scan. The deputy just looked up the plate, and the system told him where the woman was.

The ruling does not shut down Flock. It does not ban the cameras. It does not even stop the sheriff’s office from using the system. It simply says: if you are going to use it to track a specific person, you need a warrant. You cannot treat the network as a free search engine for your own curiosity or convenience.

This is about Brown and Black neighborhoods, where stops happen more often and where a plate scan can lead to a visit from the police that was never supposed to happen. This is about the cousin who parks outside the bodega and does not expect a deputy to know his exact location because a camera on a pole said so.

The ruling is narrow. It applies to one deputy, one woman, one moment. But it sets a line. If a judge can call the system indiscriminate mass surveillance, then the system is not a neutral utility. It is a surveillance apparatus — and it needs guardrails.

Why this matters for us: la gente already live under cameras, stops, and scans — this ruling means police can’t just use a plate check as a backdoor to show up at our doors without a warrant, and that’s a win we should hold onto.
