I suppose this latest lawsuit could be assessed in terms of people and institutions getting what's coming to them--Penn State allowed itself to become a karmic black hole, and so therefore it should expect noxious consequences for some time. But this is also a very good example of how a bad management culture can create effects that reverberate long after the principal miscreants have left the scene.
The failure of the University to deal with the former coach's reporting Sandusky abusing a child ten years ago continues to create fallout for the school. That initial failure led to the school removing the coach when he ultimately was identified as the key witness against Sandusky (and Joe Paterno). It was clear that McQueary couldn't continue at PSU under the circumstances. But it was also clear that his termination was fraught with legal difficulties for the school.
Damned if you do and if you don't--the only way for PSU to avoid a lawsuit was to reach some kind of severance agreement. Agreement has been in limited supply in State College lately.
