Where did you get that Paterno was only told about “horseplay”?
It was the two PennStatePedo guys who are charged for covering up the crime that reported it as “horseplay”.
From the Grand Jury report. Paterno was not told of the specifics of the rape. Only that sexual horseplay had happened. So Joe reported it up the chain of command expecting the AD to report it to his superior. That didnt happen but how was Joe to know?
