Judge: CIA Can Keep Bay of Pigs Files Secret
Volume 'Never Finished' So It Can Stay Secret. - In a ruling that could dramatically change the understanding of Freedom of Information Act (FOIA) law and historical documents and give the government and easy out for future rejections, Judge Gladys Kessler agreed that the CIA can keep the fifth volume of its history, “Internal Investigations of the Bay of Pigs Operation” secret essentially forever. Kessler agreed with the CIA’s argument that the volume was “never finished” and only exists as a draft, and that draft documents are exempt from FOIA disclosure. She also agreed with the claim that making the volume public would have a “chilling effect” on current historians, who would fear their work might conceivably be read at some future date by someone.
