Is that a realistic guess for what the sentence will be, or the theoretical maximum?
That's the maximum. They didn't mention what they will recommend. If I had to guess I would say 10 years.
It's white collar. I vote for 60 days and 3 years probation.
It's the maximum, so unless he has a prior criminal history, there is no way he will get anything resembling that. 30 years is his "whale sushi" sentence.
