A Texas man convicted of five armed robberies in Dallas-Fort Worth suburbs has asked the 5th U.S. Circuit Court of Appeals to toss his conviction and 60-year sentence. His lawyers argue that police used Flock's AI-powered license-plate camera network to reconstruct his movements without a search warrant, in violation of the Fourth Amendment. Federal prosecutors say Flock data is episodic and no warrant was required, and the court has not ruled.
