Grand jury report
In a court of law, Paterno is blameless. An assistant football coach was engaged in an illegal sexual act in the football facilities and that act was winessed by another assistant football coach. That coach told Paterno and Paterno reported it up the management food chain. It was the food chain that lied and obfuscated and killed the story.
But this all happened under the umbrella of the football program (the word "football" appears a lot in the above paragraph). And Paterno is the head of that program. It's difficult to believe that he didn't know this incident had gotten stonewalled and squashed. And that's where I have issues with him.
Like I tell my kids, real life moral choices aren't good vs. evil. It's usually doing good vs. doing nothing. It's often easiest to avert your eyes and pretend you didn't see it. Or expect someone else to do something. Paterno did nothing. And I think that was a bad choice. Particularly when he posits himself as a very moral guy. It's his program and he needed to make sure the right thing happened. And he didn't.
