James Corbett comes close but his time is primarily allocated to zoomed-out big-picture research, so there's many important pieces that barely even make it onto his radar.
There's gotta be at least one other person out there somewhere with similar abilities but more time (eg, someone retired, financially secure and no wife & kids to deal with).
All the bad in the world is orchestrated by dark forces/archons that infest the minds of individuals. In other words: there is no one individual on earth who is the evil mastermind behind all of the nefarious activities.
The flip side to that must then be also true: there is no one individual who can piece together and trace all the nefarious activities.
The one person I have found who has come close, is Joseph P Farrell
Four dozen books, all thoroughly researched and footnoted, dozens of speeches/podcasts, and countless online articles that are of book-quality make me admire him.
