Sure, and I don't necessarily think there was any real attempt to cover-up what happened (contents of the letter notwithstanding). I'm sure that the university deals with far more sexual assaults on campus than we realize. And I'm sure that most often the young woman does not want to press charges. The administration/AD/Dino might have felt that that was the way that this one was playing out and let things take their course.
They probably also felt that the woman was properly apprised of her rights as a victim and could make the appropriate decision for herself regarding criminal or civil prosecution. She and her parents should be able to easily comprehend that Wake Forest does not have a state penitentary building or courthouse on campus and that filing a criminal complaint is their job, not the uinversity's.
The worst that was ever going to happen in a J-Board trial was that someone was going to get kicked out of school. And if those J-Board losers kicked soemone out of school for sexual assault on a he said-she said accusation, they'd be the ones having their ass dragged throught he mud, along with the university, and the young woman too.
