I'm sure deep down they know that more likely than not there won't be anything found that proves Joe was in on it. He didn't build up that bull[Mark May] image and that CFB empire of his because he was a dumbass. I'm surprised they even found as much as they did. So if they can just act like they want the truth no matter what to come out, they can assume moral superiority when nothing ever comes from that.
Was Joe in on it? The testimony, from more than one source, on more than one occasion, is already there: Joe was made aware. Joe was aware. The entire chain-of-command, from janitor, to assistant coach, to campus police, to AD, to VP for security, to University President, to head football coach, were aware.
In fact, Joe was so aware that he removed his Defensive Coordinator and man deemed to be his successor from his staff in 1999 - but allowed him to keep his "emeritus status" and keys to the Flasch facility- and then ordered him to stop using university facilities a few years after that.
The circumstantial evidence created by those two acts leads to a conclusion that Joe knew, the university knew, the state government knew and yet no one took the steps necessary to stop it and prevent others from being abused. No one.
All of them failed to adequately investigate, to inform up and down the chain, to make recommendations - except, have a good weekend, and let's keep this under wraps and we should consider keeping Jerry from using our facilities. No one in the chain, including Joe, acted in a conscionable manner to make sure the abuse was stopped, investigated, reported and any one thought to be guilty prosecuted. No one.
I don't know what the legal ramifications are for a public university, but I do know that if this had been a public high school every person in that chain-of-command who was told what was going on, or even told what was suspected of going on, and failed to act could/would have been found negligent. Their certificate to teach or administrate would have been revoked and they would have found themselves open to possible prosecution. In fact it is only when high school administrators become aware that one of their students has been abused by Sandusky that any effective action is taken.
Here's a timeline that few on the BW site want to acknowledge:
