Translation: "It's just not fair to question my integrity just because I fabricated a teeny-tiny major part of my evidence."
The report itself, if I read academic-speak as well as I did 30 years ago, is absolutely devastating. A graduate student who turned in work that flawed would have been tossed out in my time, and would never have been able to get into another graduate program of any kind. He should never work as a scholar again.
