The text considers legal aspects of a broad range of methods that governments have for fighting terrorism, including criminal penalties, economic sanctions, immigration restrictions, military force, and civil liability. It addresses not just the steps taken in reaction to the 9/11 attacks, but also to many other counter-terrorism measures by the United States and other nations in recent years. To offer a global and comparative perspective, the materials include cases from foreign countries and international tribunals. The revision addresses many new legal developments that have occurred since publication of the original edition, including new Supreme Court decisions and federal legislation.
