A pertinent question would be why were these 2,800 files classified (until now)?
And would the other 300 files - even if released today - answer the questions to which many seek? Likely not…
(possibly those 300 files may contain working protocols and policies still in place today, or possibly names and locations still in use, of which could be linked or other cases & events - so could well be the reason as to them still being redacted or omitted?)
