"I interviewed Bill Peikney, who was CIA station chief in Islamabad from 1984 to 1986 , and Milt Bearden, who was CIA station chief from 1986 to 1989. These two men oversaw the disbursement for all American funds to the anti-Soviet resistance. Both flatly denied that any CIA funds ever went to bin Laden. They felt so strongly about this point that they agreed to go on the record, an unusual move by normally reticent intelligence officers. Mr. Peikney added in an e-mail to me: “I don’t even recall UBL [bin Laden] coming across my screen when I was there.”
The question Mr. Peikney should answer is:
Mr. Peikney, to the best of your recollection, who was the the person at the helm of Maktab al-Khidamat (MAK) in 1984-86, at the time you were station chief in Pakistan? Do we know that person today as Osama Bin Laden?
This article is an example of plausible denial.
