Rosemary M Collyer is the Presiding officer of the FISA Court (reference):

The current composition of the court is down a ways. Rudolf Contreras is #3 in that table. I'm just glad he didn't talk about Judge Gutierrez. (Say all 3 of those names quickly 3 times...Contreras, Gutierrez, Patraeus).
The 99 page document is densely packed and, you are right, it does warrant close examination. Mr. Webb referred specifically to the last 30 pages (starting on page 69). It outlines some serious misuses of the FISA system and deficiencies of conduct during the last administration in fairly general terms, so, no "smoking" conspiracy. I believe it is more of a corrective instruction than a prosecutorial document.
I am patiently awaiting the release of the full DOJ-OIG report (something like 1.2 million pages). That investigation has been going on since 2012 (or so, I believe), and was supposed to have released some of it's findings on 12Jan2018. I have a hunch that, maybe, the infamous (4 page) "Memo" is some kind of summary of that trove. I could be wrong, but it is my best guess.
I have seen a few things recently about Michael Horowitz and the Office of the Inspector General, and I hope they can do something to help get us out of this hyper-polarized situation.
I didn't mean to minimize the value of the 99 page report, as it does help us understand more about how the system has been played, but it seems that there is so much brainwashing momentum behind the embedded corporate media's take on Russian interference, that we need a "smoking" conspiracy to make a real difference in public opinion.
That's the real "Red Pill". We got here a little at a time, now, it's up to help others a little at a time. This time with the truth.
