Respectfully, that's not what the Grand Jury Presentment says. There was no immediate reporting by Paterno, and Paterno didn't involve the police. Joe Paterno spoke with the graduate assistant on a Saturday morning and then immediately met with the graduate assistant in JoePa's home.
Joe Paterno waited until Sunday to contact AD Curley, and only AD Curley.
Also, the graduate assistant apparently reported anal rape to Paterno; Paterno apparently reporting fondling or inappropriate sexual contact to Curley.
He took away Sandusky's keys for anally raping a ten-year-old boy in the Penn State showers.
That's even tougher than Double Secret Probation.
