Interesting fact.
It is, isn't it?
When it came time for the feds to put up or shut up, they took their ball and went home rather than have a respected third-party investigation prove their original case was based on a pack of lies.
Thus, the reason why they needed the FLIR video 'debate'.
They needed to divert attention away from the hard evidence, such as the 'machine guns' and the bodies, which proved their crimes.
