As Federal Court Rules ALPRs are Mass Surveillance, EFF Gets Disappointing Ruling
A California trial court dismissed SIREN v. San Jose, a case brought by the EFF and ACLU of Northern California challenging San Jose's warrantless searches of automated license plate reader data. The organizations say the ruling conflicts with Supreme Court precedent on data aggregation and plan to appeal.
Why this matters: License plate readers are everywhere now, and they do not just log one trip. Over time they build a detailed map of where you go, how often, and when. San Jose has a large store of that data and has been searching it without a warrant. A court just said that is fine. That conflicts with what the Supreme Court has said about how aggregated location data works differently than a single snapshot. This ruling is not the end of the fight, but it means the surveillance keeps running while the appeal plays out.
