One has to wonder if he baited them into this whole thing.
They went right to the safe as if they believed it had something in it. Nothing.
He just has boxes filled with paperwork with big red stamps, Crossfire Hurricane. They just start grabbing it all only to find out it’s all pumpkin pie recipes.
But they did, apparently, get some attorney-client stuff and that is no bueno. And with that, if there’s some type of leak about something that could only have come from some of that paperwork, he’d have them dead to rights. Kind of like when they caught that Wolfe guy by identifying certain markings on paperwork so they were able to tell where it came from.
And of course, given that he legally declassified so much, perhaps all they got were the copies he left out for them.
IIRC Wolf escaped without being charged in that incident, most likely because he was just following orders from above.
