On November 10, 2026, the ACLU and EFF filed an amicus brief in the Sixth Circuit court for the case United States v. Sturdivant. This case involves police tracking a suspect's movements using Automated License Plate Reader (ALPR) data without a warrant. The brief argues that such tracking constitutes a violation of the Fourth Amendment. The case stems from a series of robberies in Cleveland, Ohio, where police identified a suspect's vehicle through ALPR data after initially lacking the license plate number. The district court ruled that the suspect had no reasonable expectation of privacy regarding his license plate, as it is visible to the public. The amicus brief contends that ALPRs provide law enforcement with extensive surveillance capabilities that go beyond mere observation of a passing vehicle.
