I was not aware of that. My point though to a degree still stands. If it was the first e-mail, in my book the instructor could have just ended this all with, "You know I can't tell you about that coach. Don't ask again." Done. I don't have all of the information though so don't know if he was in fact pressuring the instructor beyond the idea that asking at all is pressuring.
Obviously Flood has broken the rules but there is a difference between "Is there something we can do?" and "If you don't pass him, I'll get you fired." It just seems they're looking for a forest fire here when it was just a match. (This should not be looked at as advocating academic fraud.)
