Disagree, of all the parade of despicable scumbags in this story, Paterno bears the least culpability. He reported the abuse when it came to his attention and is not in any way, shape, or form a target of the criminal investigation.
I can understand the argument that he should have done more or did not pursue the matter vigorously enough, but that is a moral failing, not a criminal or institutional violation. They really had no grounds to fire him because there was no actual breach of contract on his part.
I don't think he is getting off easy at all, he's being forced to retire under a cloud of disgrace and his legacy will forever be tainted, right or wrong, because of this shameful tragedy. And more to the point, I do believe he is devastated by everything that has happened and will bear a lot of regret and sorrow over this until the day he dies.
Sandusky should simply be beaten to death with a ballpeen hammer, cut into pieces, lit on fire, and dumped into a landfill with the rest of the filth. Abhorrent piece of garbage.
