He can't -- that's why he posts pictures. Nor can anyone.
The cover-up here was not between Curley, Schultz, Spanier and Paterno but between Emmert, Freeh, and Erickson.
Why were they in a hurry to put this all behind them and not conduct a full open investigation???
And why did Freeh refuse to interview Paterno before he died???
You want an open investigation? Really? Be careful what you wish for.
Paterno knew what Sandusky was up to and he did little to nothing to stop him. Maybe he didn’t orchestrate the cover-up, but he was certainly complicit in it’s success.
He chose to protect his football program instead of those young boys.
