Well, the import of the list is going to require some statistics. Right now I’m slammed to do all myself. Doesn’t require full up analysis of 35,000 cases. A representative sampling plan could require several hundred taken from a random sample. Will revisit in a week or so.
To get at its nature will require dividing labor, asking members to read through certain line item sections and deem scandalous or not, etc. Off the top, if a random sample of 300 would suffice, asking each willing member to read say 10 line items entails a project team of 30 members. For increased validity, a separate team could read the same sample with the two teams crosschecked to each other.
The list in the OP has ZERO to do with the 35,000 sealed filings. The "confirmed resignations/retirements/deaths" tab has 3186 lines, Line 1 being headings. Some of the references would be a slog to dig through, e.g., the Select Medical Holdings resignation on line 540 is (supposedly) reported on a linked Form 8-K, and I'm not sure that report is even going to give a reason, more likely a simple announcement.
Searching the sealed filings requires getting into the federal court docket system. Not daunting, but not nearly as easy as the file in the OP makes researching resignations. Each court has many cases, and the docket for any given case could have hundreds of line items. Footnote 1 in the 09/21/2006 Memo and Opinion in the Libby case, for example ...
In connection with these hearings, the following papers have been submitted to the Court: (1) the Defendant's Consolidated CIPA S: 5 Notice ("Def.'s Notice") [Doc 127 (classified)]; (2) the defendant's Memorandum Concerning Use, Relevance, and Admissibility of Classified Documents and Information Listed in Defendant's Consolidated CIPA S: 5 Notice ("Def.'s Mem.") [Doc 128 (classified)]; (3) the Government's CIPA S: 6(b) Notice ("Gov't's Notice") [Doc 133 (sealed)]; (4) the Government's Memorandum in Opposition to Defendant's Arguments Regarding the Use, Relevance, and Admissibility of Classified Documents ("Gov't's Opp'n") [Doc 141 (sealed)]; and (5) the defendant's Reply Memorandum Concerning Use, Relevance, and Admissibility of Classified Documents and Information Listed in Defendant's Consolidated CIPA S: 5 Notice ("Def.'s Reply") [Doc 143 (classified)].
I'd be surprised if 20% of the 35,000 sealed filing are/were indictments, and of those, I would think most were unsealed within a month or less of being filed - sealing being done to facilitate arrest of defendant.
None of that precludes the existence of 20 sealed indictments, those being Obama, Hillary, Comey, etc. It doesn't take a big number of indictments to get a small number of defendants.
