it says it's a sanitized and unclassified copy. Makes me wonder what was in there that was objectionable.
I appears to all be there from what I read. I think by saying it has been sanitized means that they just reviewed it and allowed it to fly as is and good to go with an approval stamp.
But something you NEVER do is download files like PDF’s from a government site, just going there and reading is risky enough, let alone purposely downloading files and what might be included and hidden in these files.
Better to search around and find a source for it that is not linked to a government site.
I learned the hard way many years ago...
