We're Asking an Appeals Court to Require a Warrant for ALPR Searches

The Electronic Frontier Foundation and ACLU filed a brief in federal appeals court arguing that police must obtain a warrant before searching Automated License Plate Reader (ALPR) databases to track suspects' movements. The case involves a robbery investigation where Ohio police used ALPR data without a warrant to track a defendant's car near crime scenes, raising Fourth Amendment privacy concerns about mass surveillance technology that can retrieve detailed location histories with minimal oversight.
