I've only scanned a dozen or so documents at random, and most of it is pretty low level, but adversary analysts could probably glean some useful intel about how the CIA/FBI operates from it - less usefully this amount of time on though so no real reason not to divulge.
That's what makes me think there is still stuff that is yet to come out - this isn't everything.
I know it's wiki, but it's a starting point
https://en.wikipedia.org/wiki/Malcolm_Wallace
sentenced Wallace to a five-year sentence that was suspended
So, caught pretty much red-handed for a murder and was let off?
Why am I not surprised.
However Wallace's fingerprints were never mentioned by the Dallas PD to have been found near or around Oswald's snipers Nest
Something to look for in the files later, hopefully.
Looks like total bullshit to me. No way to verify any of the statements made in this clickbait video.
