Mr. Bowron is the mayor of Los Angeles in the early 1940s. After the Japanese bomb Pearl Harbor in 1941, Mr. Bowron testifies in front of Congress on the matter of what to do about Japanese Americans. He believes that Japanese Americans—no matter how many generations they’ve been in the U.S.—are “nonassimilable” and he believes that any person of Japanese ancestry is loyal to Japan. In this way, he fuels the anti-Japanese hysteria that ultimately leads to Japanese internment.
