Il s’agit de la conférence de presse de septembre 2006.
Et le propos en question parle d’attentats contre des batiments US en général, il n’est pas fait référence au 11 septembre en particulier :
"For example, Khalid Sheikh Mohammed described the design of planned attacks of buildings inside the U.S. and how operatives were directed to carry them out. That is valuable information for those of us who have the responsibility to protect the American people. He told us the operatives had been instructed to ensure that the explosives went off at a high — a point that was high enough to prevent people trapped above from escaping."
