From the document below:
“This reconstruction of Agency involvement in plans to assassinate Fidel Castro is at best an imperfect history. Because of the extreme sensitivity of the operations being discussed or attempted, as a matter of principle no official records were kept of planning, of approvals, or of implementation.
The few written records that do exist are either largely tangential to the main events or were put on paper from memory years afterward.”
In July of 2016, The Black Vault filed a Mandatory Declassification Review (MDR) request for this record. Although previously released, it was heavily redacted. The most recent known version at the time of filing, was THIS ONE, appearing to have been last reviewed in 2002.
In March of 2019 (added to The Black Vault on December 16, 2020), the below record was reviewed for release.
There are less redactions, but more so, the copy is much more legible.
