>>I don't know if anyone mentioned this yet (hard to keep up with it all)
There is an enormously obvious word-processing insert on this memo: http://www.cbsnews.com/htdocs/pdf/BushGuardaugust18.pdf
Where is says "Austin is not happy today either"
The "not happy today either" drops down to the next line and is in an easily obvious different font from the entire rest of the document
Great find! There are two different fonts being used in some of the documents. In your example, look at the "tin" in "Austin" and the "tin" in "rating" just above it. The fonts are different.
