He did the minimum to cover himself legally.
Accusations like this are the reason to defend Paterno.
You are claiming that Paterno was trying to protect himself and cover up a scandal. There is absolutely no reason to think that other than some perverse desire to believe the worst.
Me, I think Paterno was forwarding a report of possible crime to those equipped to determine the reliability of it and then notify the proper authorities.
Could I be wrong? Sure.
But it's one thing to point out more reasonable explanations in defense of one charged with wrongdoing than it is to accuse someone of wrongdoing without a scintilla of evidence.
