According to three officials with access to the report, Fine said the possible violations he discovered did not “manifest deliberate attempts to circumvent statutory limitations or departmental policies.”
But Fine found that FBI agents used national security letters without citing an authorized investigation, claimed “exigent” circumstances that did not exist in demanding information and did not have adequate documentation to justify the issuance of letters.
In at least two cases, the officials said, Fine found that the FBI obtained full credit reports using a national security letter that could lawfully be employed to obtain only summary information. In an unknown number of other cases, third parties such as telephone companies, banks and Internet providers responded to national security letters with detailed personal information about customers that the letters do not permit to be released. The FBI “sequestered” that information, a law enforcement official said last night, but did not destroy it.
