A San Diego man spent nearly a month in jail for an attempted carjacking he did not commit, all due to a false alert from a Flock Safety license plate reader. The system flagged Parra’s car, which was five miles away, just 23 seconds after the actual crime, making it physically impossible for him to have been the perpetrator. Police relied on the “vehicle fingerprint” technology, which scans for make, model, and visual features, instead of verifying the timestamp. This incident highlights how surveillance technology can contribute to wrongful arrests through confirmation bias and flawed data. Parra and another affected individual are seeking $1.5 million in damages, warning that “mass surveillance without any sense of skepticism, or common sense, is a recipe for disaster.” Similar errors have occurred elsewhere, demonstrating a pattern of system failures with potentially devastating consequences for civil liberties.
