Police arrested Hom Way for possession of heroin. While under arrest, Way told police that a man named “Blackie Toy” once sold him an ounce of heroin at his laundry on Leavenworth St. Later that day, police found a laundry run by James Wah Toy. Nothing on the record identified Toy as “Blackie Toy”, but police arrested him anyway. Police then went to Toy’s house where they arrested Johnny Yee and found several tubes containing less than one ounce of heroin. Police also arrested Wong Sun. Police interrogated the men and wrote statements in English for them to sign. Both men refused, citing errors in the statements. At trial in U.S. District Court, Toy and Sun were convicted on federal narcotics charges. On appeal, the U.S. Court of Appeals for the Ninth Circuit affirmed. Under "Probable Cause", were the searches and arrests legal
