The following document was first released to the National Security Archive circa 2015. There were some redactions, so The Black Vault filed a Mandatory Declassification Review (MDR) case on November 27, 2021. Since the document was only a few pages, it took only about a month to complete.
However, this MDR case was a little strange. In most cases, an MDR “success” is when redacted are lifted, even in part. An MDR “failure” is when nothing changes. This? Not sure what you call this, but additional redactions were ADDED, and not removed.
In a rather humorous (albeit frustrating) outcome, I highlighted both releases below so you can see what they felt the need to cover-up now vs. not cover up in the past.
