... A senior intelligence official described the details only on condition of anonymity
Everything described in "great detail" except -- the source.
In other articles they mention the recent capture by Pakistan of a high level Al Qaeda operative.
It's a good thing the Pakistanis captured him, if we had, we would be giving him a lawyer, and would not allow to interrogate him, other than ask him nicely, if he cared to share any info with us, and you know how much info we would get.
Drudge just put up a siren saying that it's an Al Quada computer geek.
