Book excerpt: In her groundbreaking new book, Silencing Political Dissent, constitutional expert Nancy Chang examines how the Bush administration's fight against terrorism is resulting in a disturbing erosion of First Amendment rights and increase of executive power. Chang's compelling analysis begins with a historical review of political repression and intolerance of dissent in America. From the Sedition Act of 1798, through the Smith Act of the 1940s and the internment of Japanese Americans in World War II, to the FBI's infamous COINTELPRO program of the 1960s, Chang recalls how during times of crisis and war, the U.S. government has unjustly detained individuals, invaded personal privacy, and hampered the free speech of Americans. Chang's expertise as a senior constitutional attorney shines through in the power and clarity of her argument. Meticulously researched and footnoted, Chang's book forces us to challenge the government when it is unpopular to do so, and to consider that perhaps "our future safety lies in the expansion, rather the contraction, of the democratic values set forth in the Constitution."
