Details of a secret FBI report, from [1] ABC News, with thanks to Jeffrey Imm and RB:

"Al-Qa'ida leadership's intention to attack the United States is not in question," the report reads. (All spellings are as rendered in the original report.) "However, their capability to do so is unclear, particularly in regard to 'spectacular' operations. We believe al-Qa'ida's capability to launch attacks within the United States is dependent on its ability to infiltrate and maintain operatives in the United States."

And for all the worry about Osama bin Laden's sleeper cells or agents in the United States, a secret FBI assessment concludes it knows of none.

The 32-page assessment says flatly, "To date, we have not identified any true 'sleeper' agents in the US," seemingly contradicting the "sleeper cell" description prosecutors assigned to seven men in Lackawanna, N.Y., in 2002....

It also differs from testimony given by FBI Director Robert Mueller, who warned in the past that several sleeper cells were probably in place.

"Our greatest threat is from al Qaeda cells in the United States that we have not yet been able to identify," Mueller said at a Senate Select Intelligence Committee hearing in February 2003. "Finding and rooting out al Qaeda members once they have entered the United States and have had time to establish themselves is our most serious intelligence and law enforcement challenge."

When the secret report was issued last month, on Feb. 16, Mueller testified at a hearing before the same committee that the lack of evidence concerned him. "I am concerned about what we are not seeing," he said....

Yes, indeed, Mr. Mueller. So are we.
