Because they followed institutional protocol by the book. The only thing they could possibly get penalized for is the two perjury counts. BUT, all the lawyers who analyzed the pretrial testimony from last week say the chances of the perjury charges sticking are a longshot. McQueary fudged what he saw when he reported it to the head of campus police and the AD, and even if he didn't, his own doctor (whom he confided to immediately after the rape) said that he was not clear that there had been a rape, and so the standard for proving perjury is not there. The perjurors need to be convicted of intentionally deceiving law officials and jurors. This won't rise to that standard.
Otherwise, everyone involved fulfilled the institutional protocols. That is, they reported the incident to their superior until it found its way to the head of campus police.
Paterno was fired because everyone said he RUNS Penn State, so the excuse that he reported to his superior is BS. That's why Paterno was raked over the coals. But nonetheless, by the letter of the law, he fulfilled his responsibilities, and this is precisely why even the attorney general praised Paterno for his actions and testimony in the original grand jury presentment.
In other words, PSU sports officials followed the rules and regulations, but they did not go the extra mile and report it directly to police.
