I think an important question is whether the version in the LOC is the real version. Since there are so many red flags, it would make a good deal of sense that they simply placed a watered down version of the material in the LOC for a "lucky" reporter to find and take the heat off them.

Basically, this version is a sensitive detector for describing government wrongdoing, but it is not specific - it doesn't prove that certain forms of wrongdoing were not in the training manual.
