Guys, as I was, unfortunately, directly involved (as a student) to the person in question and the circumstances why he was fired, I can assure you it didn't had anything to do with a CD of any kind.
I hope you can appreciate I won't disclose any more details.
The GI in question was a very good teacher, and he will be missed. I hope he is doing well, although rumor has it he has been offered a new job somewhere else.
