According to the 9/11 Commission, on this day “A new listing for [9/11 hijacker Khalid] Almihdhar was placed in an INS and Customs lookout database, describing him as ‘armed and dangerous’ and someone who must be referred to secondary inspection.” However, this information will only first appear in a little-noticed Commission staff report released one month after the 9/11 Commission Final Report. It will not be explained who determined Almihdhar to be armed and dangerous or what information this was based on. [9/11 Commission, 8/21/2004, pp. 31 ] By September 5, 2001, the lookout database will be inexplicably changed and inspectors will be told not to detain Almihdhar after all (see September 4-5, 2001).
