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

Sturdivant involves a series of robberies in and around Cleveland, Ohio. Using surveillance camera footage, police identified the make, model, and color of the robber’s car, but they did not know its license plate number. After running an open-ended search of two ALPR databases, Flock and ELSAG, officers learned a car belonging to the defendant had been tracked near sites of the robberies, eventually leading to his arrest. Faced with a motion to suppress the ALPR evidence, the district court held that Mr. Sturdivant had no reasonable expectation of privacy in his license plate number because it could be observed by members of the public, and that therefore he had no…
