It details the ongoing FOIA lawsuit against DOJ/DOD to release any video that has been withheld of the Flight 77/Pentagon attack.
Summary: the government is apparently in possession of a single "responsive record" of the attack that has not been released to the public. This record consists of video time-lapse images from two cameras in the Pentagon parking lot. *Some* images from *one* of the cameras were leaked to CNN, without authorization, back in 2002, and these are the ones we've all seen and squabbled over. DOJ claimed a FOIA exemption because release of the remaining video endangered the prosecution in the Moussaoui trial. The trial is over, and the judge in the case has given the government until 5/26 to explain why they need to continue to claim the FOIA exemption.
According to a statement by the FBI agent who conducted the search, there were 85 (!) separate video records found (this was during the second search -- the first search turned up nothing, the government said. Plaintiff sued again and said, "look harder"). Of those, 84 didn't show the impact, according to the agent's statement -- she apparently viewed them herself. The one record that did is at the center of the dispute. The FBI agent claims there was no video from the Sheraton found, but there was one found from the Arlington Doubletree. No explanation has been given for why the 84 videos that show nothing have not been released.
After reading those court documents, I almost don't blame the CTs. It's very hard to understand the government's logic in resisting this request. If there's a national security argument (denying the enemy a real-time trajectory analysis or bomb damage assessment), they're not making it -- so far, it seems they're withholding based on legal grounds, and the fear of jeopardizing the Moussaoui trial. Of course that's over now, so that argument should be moot. It will be interesting to see how the government responds in the next few weeks.
