Not having seen the video or looked into this very much, I really had no idea one way or the other. I was just trying to think as they might in a situation like this: plant a false clue that can then be later discredited.
Understand — This video and the videographer have some answers to questions.
The Russians have done their damndest to dispute this video by calling it a hoax.
On face value without drawing any conclusions, this video raises alot of questions and the Russians don’t like that.
