This course is designed to expose students to the rapidly evolving and highly contested legal dimensions of confronting the threat of terrorism. It starts with a discussion of the definition of terrorism, and the legal frameworks that are brought to bear in confronting terrorism, which include federal legislation (including U.S. military law), U.S. constitutional law, treaty law, and customary international law. It then follows thematically the issues that arise in some sense sequentially in confronting terrorism: finding, killing or detaining, interrogating, and trying suspected terrorists. Given the professor's interests in detention, and the extent to which detention issues have been litigated, the emphasis in the course will be slightly tilted towards detention issues.
