Very interesting... but how could he "prove" that he wasn't involved other than saying "I didn't do it"?

I don't think he had to prove anything other than being willing to show up. No one has ever accused Castro of being totally stupid when saving his own skin was involved.

Yeah... he was many things... but stupid was not one of them...
