The terrorist attacks on Sept. 11, 2001, stunned the nation. As commander-in-chief, President George W. Bush responded quickly but soon all three branches of government would be embroiled in the struggle to balance national security with the protection of individual liberties amid a war on terror. This lesson plan is based on the Annenberg Classroom video “Habeas Corpus: The Guantanamo Cases.” The four cases are examples of how the Supreme Court, the president and Congress fought to balance national security and civil liberties during the war on terror. At the heart of each case was the constitutional right of habeas corpus, the right to have one’s detention or imprisonment reviewed in court.
