California trial court dismisses SIREN v. San Jose challenge to warrantless ALPR searches

A California trial court dismissed SIREN v. San Jose, a case brought by EFF and the ACLU challenging the city’s warrantless searches of automated license plate reader data. The court held that drivers have no reasonable expectation of privacy on public roads, rejecting the privacy claim. EFF plans to appeal the decision.

Why it matters: The dismissal highlights ongoing legal battles over mass surveillance via ALPRs and their privacy implications.
