I-49, a squad of FBI agents and Justice Department prosecutors that began focusing on bin Laden in 1996 (see January 1996), is upset that the NSA is not sharing its monitoring of the phone calls of Khalid Shaikh Mohammed (KSM). The squad builds their own antenna in Madagascar specifically to intercept KSM’s calls. [Wright, 2006, pp. 344] It has not been revealed when this antenna was built or what was learned from this surveillance. However, there have been media reports that the NSA monitored some phone calls between KSM and Mohamed Atta in the summer of 2001 (see Summer 2001). Further, US intelligence monitored a call between KSM and Atta a day before 9/11 that was the final go-ahead for the attacks (see September 10, 2001). So presumably the I-49 squad should have known about these calls as well if this antenna did what it was designed to do.
