The dates of Atta's travels (as 'established' by the commision) were key to concluding that: 1) Atta could not have met with Iraqi intelligence and 2) Able Danger's information was incorrect and could be ignored.
I wonder if this person's timeline could have been in conflict with the 'established' timeline. If it did, of course they wouldn't talk to him.
Somebody review those records of training, pull-eaze! This is good research...I mean after Cindy in Crawford, of course.
