Then the program turned to Marcel Matley, identified as a "handwriting examiner" with no further credentials given, who offered his opinion that the "suicide" note is genuine. Matley believes that the "deteriorated copy" of the note.... that is, it's been copied over too many times.... and the "stress" Foster was presumably under account for the differences in handwriting. He then went on to show how Foster used different styles of letters in the genuine samples, such as both cursive and block letter "s", for example, and how the same multiple styles appear in the note; and from this he concluded that the same person wrote both the note and the samples known to be genuine.
One problem with Matley's statements is that it is impossible to determine to what extent the copy of the "suicide" note used by the experts has deteriorated from the original.... because the government has yet to release any official copy of the original, much less a high-resolution one. I just don't see how Matley can point out examples of "deterioration" in copies of the note without having seen the original note.
"Matley believes that the "deteriorated copy" of the note.... that is, it's been copied over too many times...."
Exactly how Rather described the purported Killian documents.
