Sixteen years after the 9/11 terrorist attacks on the World Trade Center and the Pentagon, we still don’t know what happened. How did a ragtag bunch of hijackers, armed only with box cutters, manage to gain control of those airliners? How did they get into the United States to begin with? Who supported them while they were here? Why didn’t law enforcement – which had plenty of clues as to what they were up to – stop them? Prior to the attacks, our government spent billions on “anti-terrorist” programs designed to prevent precisely what occurred on September 11, 2001 – yet Mohammed Atta and his accomplices managed to slip through the cracks. How?
