The FBI's OIG Report On The Effect Of The Wall On The FBI’s Attempts To Khalid al-Mihdhar

I read from the FBI's Office of the Inspector General (OIG) report which was publicly released in June 2006. In this section of the chapter, The IG discusses the walls which affected the FBI personnel’s discussions about the Khalid al-Mihdhar information at the June 11, 2001, meeting in New York and the FBI’s decision to open an investigation to locate al-Mihdhar in August 2001.
