In what amounts to a fight over who gets to write the history of the Sept. 11 attacks and their aftermath, the Central Intelligence Agency is demanding extensive cuts from the memoir of a former F.B.I. agent who spent years near the center of the battle against Al Qaeda.
The agent, Ali H. Soufan, argues in the book that the C.I.A. missed a chance to derail the 2001 plot by withholding from the F.B.I. information about two future 9/11 hijackers living in San Diego, according to several people who have read the manuscript. And he gives a detailed, firsthand account of the C.I.A.’s move toward brutal treatment in its interrogations, saying the harsh methods used on the agency’s first important captive, Abu Zubaydah, were unnecessary and counterproductive.
