9/11 Commission Report Published

The 9/11 Commission releases its 567-page final report, which becomes a bestseller with over 1 million copies sold within weeks. The report concludes that the attacks were carried out by al-Qaeda under Osama bin Laden's direction, identifies systematic failures in U.S. intelligence, immigration, and aviation security, and makes 41 specific recommendations. It finds no 'credible evidence' of a collaborative relationship between Iraq and al-Qaeda. The report becomes a foundational document of national security reform.
