Riley v. California

Police arrested David Riley (defendant) and searched his smartphone, using evidence found on it to convict him of shooting-related charges brought by the State of California (plaintiff); the state court of appeal upheld the search as incident to arrest. In a companion case, police seized Brima Wurie's flip phone during a drug arrest and used information from it to get a warrant for his home, but the federal court of appeals ruled that search of the phone was illegal. The Supreme Court granted certiorari in both cases.
