Because when you are "absolved", you are absolved of "something".
Absolution has an object or wrong from which you are absolved.
Read your definition.
Spanier, Schulz, Curley, Paterno were/are accused of a coverup of Sandusky's crimes.
Is the Board of Trustees accused of the coverup by Freeh as well or are they absolved of the coverup by Freeh???
Your spin and obfuscation is immature. Read this again and explain exactly what it is that you fail to comprehend. "Freeh said Sandusky's conduct was in part a result of the school's lack of transparency, which stemmed from a "failure of governance" on the part of officials and the board of trustees.
Cut the BS and answer the question.
