Curley emailed the other two that he had given it more thought and had "talked with Joe last night" and that he had changed his mind about how to proceed with Sandusky. Clearly, it's possible that Paterno told him exactly what to do, or else. Nevertheless the possibility also exists that Paterno was fed specific and spun information and based all of his decisions on false, misleading, or incomplete facts. The report itself specifically states that it's unclear exactly how much Paterno knew about the incidents.
I think there's enough evidence to say that Paterno is certainly not "innocent", but your argument does nothing but support highhorse's in this particular instance.
