What are you talking about?!?
That guy is regarded as America's biggest pussy. A 6'3" former football player who saw an old man raping a child and ran away to ask his daddy what to do?! Nobody exonerates him. In my book, he's number 2 or 3 on the scumbag list in this affair, depending on what Mrs. Sandusky knew.
There is almost no end to the number of people who acted shamelessly in this situation. Joe Pa is up there, but he's not at the top.
Roger that.
Whatever happened to the reporter who made allegations that Sandusky was "procuring" boys for high dollar donors. That story got really quiet, really quickly.
You're right that Joe P is no saint, but there's a whole lot of blame to go around from the top on down.
