I don't see what is so wrong. The DoD frequently deals with confidential information, and some of the techniques used to sanitize documents for hardcopy release do not work for electronic release. The document describes how to delete text and reformat pages, and how to export a Word document to PDF so that metadata comments are not carried over. Basically, this is an idiot's guide on how to not do something stupid.
There's nothing WRONG with these instructions. I'm just miffed at the Barret report's missing so much data.
