You can't prove a negative Mickey. If there is proof to be shown, it has to come from Rob.
Personally I don't require that he (or anyone) show proof. But Wizard and Dan Druff did ask for proof and the "proof" Rob came up with was tying the double up to the Newell, which he then quite clearly attempted to show phony proof of....twice (at least).
No one forced him....he did that on his own. So yes, there IS definitive proof against.
