For personal reasons, I've been thinking a lot about paper trail in the legal / evidentary context lately. So I clicked expecting something about the analysis of an organizations paper trail rather than an individual. Still there are some similarities. Namely, a set of documents such that matching them with or categorizing by relation to other publicly known ones is the main puzzle, and a source of these documents that is possibly intentionally trying to obscure those relations.

What can the creation of this archive teach us about identifying corruption? I'm legit unsure, but maybe there's a relevant lesson?
