This is the 'tamsey', again - right? I don't know why you think such a complaint against Farah is credible. In fact, he claims to have seen this on his own tape, himself, after having been directed to it by others, who saw it - too. That starts to become quite a conspiracy.
Why not allow for the possibility that Joe Farah got it right, saw exactly what he claimed, didn't like what he saw, and wrote to complain?
