Decades ago, Harry Cain warned, “It is possible to become so safe that nobody can be free.” Still the conflict rages on between individual freedom and national security. C. Mark Smith’s Raising Cain profiles a complex and controversial public servant who remained true to one goal—supporting the rights of the individual. Cain opposed the internment of Japanese American citizens during World War II, defended provocative figures as a U.S. Senator, worked for civil rights in Florida, and in the controversy that destroyed his public career, defied his president and his party to protect the freedom of thousands of Americans threatened during the McCarthy era.
