Federal judge rules Flock license-plate system amounts to 'indiscriminate mass surveillance'

A federal judge has ruled that the use of Flock Safety's automated license plate reader system by a sheriff's deputy amounted to "indiscriminate mass surveillance," finding that the deputy violated a woman's Fourth Amendment rights by searching for her license plate without a warrant.

The ruling centers on how law enforcement agencies use the network of cameras, which automatically scan and log license plates as vehicles pass, to search for specific vehicles after the fact. In this case, the court found that the warrantless search of the plate database crossed a constitutional line.

Flock's camera systems have been adopted by police departments and sheriff's offices across the United States in recent years as a tool for locating vehicles connected to criminal investigations. The technology has also drawn scrutiny from civil liberties advocates, who argue that the scale and retention of the data collected raises significant privacy concerns.

The judge's characterization of the system as indiscriminate mass surveillance is likely to be cited in future legal challenges to similar license-plate reading networks, as courts continue to grapple with how Fourth Amendment protections apply to large-scale, automated data collection by law enforcement.

It remains to be seen how the ruling will affect the broader use of Flock's technology by other law enforcement agencies, or whether it will be appealed. Flock Safety has not yet issued a detailed public response to the decision.

The case adds to a growing body of litigation testing the legal boundaries of automated surveillance tools used by police departments nationwide.
