Oh how easy it would be to live in a world of black and white.
Nobody is saying Paterno wasn't wrong in things he did and didn't do. But these situations are not as easy as some people make them out to be. And the lack of realization about this is one of our major problems as a society and justice system in regards to pedophilia.
One of the major problems with society is that there are people like Sandusky, and that there are people that not only do nothing to stop them, but even facilitate them by putting them in a situation where they has easy access to children.
You're right, the world is not black and white. But this case is. Molesting children is wrong. There are no situations where that is ok - it is black and white. And, if you see it happening, you should do something about it. There are no situations where it is ok to not do anything about it. That, to me, is also black and white. If the powers that be do nothing about it, then you do something yourself. Especially if you are Joe-freaking-Paterno, who (let's face it) was the real boss at Penn St. If nothing else, he should have fired that guy immediately and not let him have direct access to children anymore. What they did is unforgivable.
