The declassified documents, dated between 1992 and 2004, are heavily blacked out and offer little new information about what the U.S. knew about the al-Qaida plot before 2001. Many of the files are cited in the 9/11 Commission report, published in 2004.
The commission determined the failure that led to 9/11 was a lack of imagination, and U.S. intelligence agencies did not connect the dots that could have prevented the attacks.
Though few new details are revealed in the documents, the files offer more historical context for the years surrounding the deadliest terror attack on U.S. soil.
The National Security Archive obtained the documents through a Freedom of Information Act request and published them on its website Tuesday. The archive is a private group seeking transparency in government.
An April 2000 document from the CIA's bin Laden unit alluded to a budgetary cash crunch that was cutting into the agency's efforts to track the terror leader.
TVNL Comment: More nonsense fed to the public in support of the 'official' story of 9/11. You only believe it if you don't KNOW the official story.
