The “missing” videos would show cell members who are inconsistent with the official narrative (e.g a Filipino Muslim and some others not previously known to the public).
The videos would probably also show a secondary explosion caused when an illegal military weapons cache that was located in the building cooked off.
I would expect copies of some of the missing videos will be found - in the storage unit of a retired FBI agent after following the instructions from a posthumous note
Video recordings is one thing that today’s law enforcement should not be permitted to touch in any form or fashion. For whatever reason, their “How to handle evidence” course when it pertains to videos just didn’t penetrate deeply enough for retention.
I cannot help but think of 9/11 and the Pentagon. 1 1/2 seconds of the sorriest video is displayed as evidence.
If I was this judge I would be tempted to bring in every retired agent who ever worked on this case that I could find for testimony. Start seeing if you can’t get somebody on perjury.
