Jack Bauer is a key member of CTU and is often portrayed as their most capable agent. Bauer's job usually involves helping prevent major terrorist attacks on the United States, saving both civilian lives and government administrations. On many occasions Jack does so at great personal expense, as those he thwarts subsequently target him and his loved ones. He is not a crooked agent, however Bauer's frequent use of torture to gather information has generated much controversy and discussion.
