Taking control of intelligence.

When it comes to NSA and the use of intelligence, about the best thing you can say for the Bush administration is that they took the last few shreds of efficient information coordination in Washington and shredded them further by seriously overloading them with wild goose chases.  The question remains:  are they doing it deliberately?

I think they are.  And by now we ought to have a sense of the bigger picture.  Do we?

The N.S.A.'s legal authority for collecting the information it passed to the F.B.I. is uncertain. The Foreign Intelligence Surveillance Act requires a warrant for the use of so-called pen register equipment that records American phone numbers, even if the contents of the calls are not intercepted. But officials with knowledge of the program said no warrants were sought to collect the numbers, and it is unclear whether the secret executive order signed by Mr. President Bush in 2002 to authorize eavesdropping without warrants also covered the collection of phone numbers and e-mail addresses.

Aside from the director, F.B.I. officials did not question the legal status of the tips, assuming that N.S.A. lawyers had approved. They were more concerned about the quality and quantity of the material, which produced "mountains of paperwork" often more like raw data than conventional investigative leads.

"It affected the F.B.I. in the sense that they had to devote so many resources to tracking every single one of these leads, and, in my experience, they were all dry leads," the former senior prosecutor said. "A trained investigator never would have devoted the resources to take those leads to the next level, but after 9/11, you had to."

By the administration's account, the N.S.A. eavesdropping helped lead investigators to Iyman Faris, an Ohio truck driver and friend of Khalid Shaikh Mohammed, who is believed to be the mastermind of the Sept. 11 attacks. Mr. Faris spoke of toppling the Brooklyn Bridge by taking a torch to its suspension cables, but concluded that it would not work. He is now serving a 20-year sentence in a federal prison.

But as in the London fertilizer bomb case, some officials with direct knowledge of the Faris case dispute that the N.S.A. information played a significant role.

The administration's uses of misinformation and chaos are well-documented.  For some recent thoughts on the promotion of instability and lousy management in other areas, read this.
