Former FBI agent Ali Soufan says he has not been allowed to tell the truth about 9/11. Soufan is a Lebanese man who came to the US as a teenager and is one of the few Arabic speakers in the FBI. He says that not only were we mislead about what lead up to 9/11 and what could have prevented it, but he argues that rough interrogation techniques, such as water boarding, were unnecessary, since he and his team had ALREADY GOTTEN the information about al-Quaeda that these methods were trying to elicit.
When the 9/11 attacks occurred, Soufan was in Yemen investigating the earlier bombing of the USS Cole. The next day, a CIA officer in from the US embassy there passed him an envelope which told about links between the people he was investigating for the warship bombing and two of the hijackers, who had been living in the US for months before the attack.
In BBC News, Gordon Corera and Steve Swann quote Soufan as saying, "People in our government knew that they were here–we were not told. We were looking for them overseas. They were here. People in our government knew that they were here. We were not told." Soufan has interrogated suspects and says he was able to extract valuable intelligence with traditional interrogation methods, without using techniques such as water boarding, nudity, sleep deprivation and stress positions.
He was the first person to question Abu Zubaydah, who identified Khalid Sheikh Mohammed as the mastermind behind the 9/11 attacks. But Washington believed Abu Zubaydah knew more, so they sent out a CIA contractor to use "enhanced interrogation techniques."
