Certainly his "story" has been fairly consistant throughout, although I must confess that I have not followed it that closely, and that generally indicates some element of truth. He has not introduced any other matters apart from those he originally cited.
What DaveR says is certainly plausible, but if such were the case, why does Hunt carry on with his crusade knowing that in the end he will not succeed? He is either on a hiding to nothing or living in the vain hope of raking in a tidy sum by way of compensation. Either way I'm not too interested. ZXZ
