The FBI disclosed to a presidential board that it was involved in nearly 800 violations of laws, regulations or policies governing national security investigations from 2001 to 2008, but the government won't provide details or say whether anyone was disciplined, according to a report by a privacy watchdog group. The San Francisco-based Electronic Frontier Foundation sued under the Freedom of Information Act to obtain about 2,500 documents that the FBI submitted to the President's Intelligence Oversight Board. Most of the records were so heavily censored that they couldn't be properly evaluated. Nevertheless, the documents "constitute the most complete picture of post-9/11 FBI intelligence abuses available to the public," says the report. "The documents suggest," the report says, "that FBI intelligence investigations have compromised the civil liberties of American citizens far more frequently, and to a greater extent, than was previously assumed." The records obtained by the foundation go beyond national security letters. About a third of the reports of violations involved rules governing internal oversight of intelligence investigations, and about a fifth involved potential violations of the Constitution, the Foreign Intelligence Surveillance Act or other laws governing criminal investigations or intelligence-gathering activities, the report says.
