"My story is consistent"
Interesting. does he think others' stories aren't?
"The former contractor, James D. Smith, said that Mr. Atta's name and photograph were obtained through a private researcher in California who was paid to gather the information from contacts in the Middle East."
Doesn't sound much like data mining, but old fashioned-humint.
"Mr. Smith said that he had retained a copy of the chart for some time and that it had been posted on his office wall at Andrews Air Force Base. He said it had become stuck to the wall and was impossible to remove when he switched jobs."
Oh yeah, the old "sticky wall" excuse. He should have just said he didn't think to take it. Instead he creates a story where no poster will be found on his old wall, therefore there was a conspiracy.
Weak stuff.
Mr. Di Rita said in an interview that while the department continued to investigate the assertions, there was no evidence so far that the intelligence unit had come up with such specific information about Mr. Atta and any of the other hijackers.That is very heavily qualified denial.
If he taped it to the wall with regular, not "magic" cellophane tape, that does tend to form a pretty strong bond, stronger than the paper, after not all that long. Anyone who's ever been in an office or cube for a goodly period, and taped stuff to the walls, knows this. Double sided tape, or the old trick of making a loop of regular tape with the sticky side out, can be even worse.
