Finally, the answer to the question people have asked since 9/11: "How DID the terrorists enter the United States?"

Before 19 hijackers could commit the terrorist attacks of September 11, 2001, they passed through U.S. border security 68 times. In all, they had 25 contacts with consular officers and 43 contacts with immigration and customs authorities—none of whom suspected they were al Qaeda operatives.This book includes the complete staff report Time.com called "tantalizing and important" and represents important investigative work by the staff, providing substantial information and analysis not fully represented in The 9/11 Commission Report.Now for the first time in book form, this report includes:
