âCity on a Hillâ actress Keiko Elizabeth said that when she was cast as Karen Shimizu â a U.S. attorney who had grown up in an internment camp during World War II â she had the unique knowledge of talking to someone who had experienced that firsthand: her father. âMy dad is simultaneously very idealistic and very cynical about the American justice system and I really wanted to illuminate that paradox,â said Elizabeth, who resides in California. âKaren is a woman who, in spite of having experienced the worst of the American justice system, is committed to improving it from the inside. And that commitment is the source of (her) power and the root of (her) conflict with Jackie Rohr (played by Kevin Bacon).â
