First of all, I have to laugh at the use of the word "audience" in the OP, as if it would be some sort of "privilege" or "honor" to talk to them.
I recognize no authority higher than myself and all 7 of those guys are much further down the list than the majority of humans I know.
That being said, if I had the opportunity to ask them a question it would be this: "How can you stand to live with yourself? You're such a hypocrite and you've destroyed so many lives! You represent everything you publicly claim to condemn!"
Then, I suspect they would ask me for mercy ...
In all likelihood, neither of us would get the answers to our questions.
