Let's say someone in DC or someone long-affiliated with the federal government is suddenly wracked by guilt. They need to clear their conscience by telling the truth of what they've done, seen, or been complicit in. You're called to interview them, and they'll be 100% honest. Who would you want this person to be, and what would you ask them? Before he died, I would've said George H.W. Bush, because he was (bafflingly) at the center of so much American political malfeasance for decades. I'd want to know about the October Surprise, Iran-Contra, CIA-crack scandal, the Carlyle Group, and Saudi connections before 9/11. I mean, can you imagine how many conspiracy theories he could've affirmed (or laid to rest), saving a lot of people the mental energy in speculating? Anyway, who's someone living who'd be a goldmine?
Obama would be interesting, i'd want to see if he believes his own bullshit or if he's like "The Smiler" from Transmetropolitan.
