A confidential informant tells an FBI field office agent that he has been invited to a commando-training course at a training camp operated by al-Qaeda in Afghanistan. The information is passed up to FBI headquarters, which rejects the idea of infiltrating the camp. An “asset validation” of the informant, a routine but critical exercise to determine whether information from the source was reliable, is also not done. The FBI later has no comment on the story. [US News and World Report, 6/10/2002] Around this time, John Walker Lindh, a Caucasian US citizen who recently converted to Islam, goes to one of the training camps for the first time and learns details of the 9/11 in a matter of weeks (see May-June 2001). Also around this time, seven men from Lackawanna, New York, go to a training camp in Afghanistan and hear clues about the 9/11 attacks before they drop out after only a few weeks (see (June 2001)).
