Security V. Liberty

Book excerpt: Explores the varied ways in which threats to national security have affected civil liberties throughout American history. Has the government’s response to such threats led to a gradual loss of freedoms once taken for granted, or has the nation learned how to restore civil liberties after threats subside and how to put protections in place for the future? The authors focus on periods of national emergency in the twentieth century—from World War I through the Vietnam War—to explore how past episodes might bear upon today’s dilemma. They show that civil liberties are a not an immutable right, but the historically shifting result of a continuous struggle that has extended over two centuries. From publisher description.
