You do have a difference - a sans serif font in header and than serif (Times Roman ?) in the body. Could have prepared something off line and pasted into the email, either as serif text or as an image.
It is an extensive email, sprinkled with "journalists" in quotes, indicating a not so subtle slam. I expect Nifong enjoyed working on it.
My take just from the letter is that he enjoys seeing/ hearing himself talk and is immature.
