I'm not sure how many of us would take any additional action after reporting a crime to the police. I would assume the police would investigate and take the appropriate action.
These kind of allegations are tricky for the police. People will give different accounts of what happened. The identity of the young man was apparently unknown. Without a victim or physical evidence, it would be practically impossible to obtain a conviction. So my impression isn't that there was a cover up of the crime, but that the police conducted an investigation but were unable to gather enough evidence to convict this scumbag Sandusky. Or it could be that someone high up in university administration convinced the police to lay off the investigation -- Paterno wouldn't be involved in the investigation or know the details.
While some university officials apparently failed in their obligation to report things to appropriate child welfare agencies (and hence criminal charges against them), the prosecutors are satisfied that Paterno did what he was supposed to do, and they have stated as much. We don't really know what all Paterno knew or what he did -- he has been practically muzzled by the ongoing investigation and flocks of lawyers. The coach who witnessed the event, however, said that he did not provide specific details to Paterno, out of respect for the coach's age.
We also don't know how much control Paterno had over subsequent events or the university's actions. Coaches don't control university policies -- indeed, they can be fired on a moment's notice. Some people higher up than Paterno apparently tried to keep the matter quiet, and these are the individuals the police are now going after.
Furthewr reason why Paterno should have taken McQueary and gone to the Po Pos right that minute. Not whenever it was convenient. We all know what really happened. Paterno and everyone else had been turning a blind eye to the "Sandusky Problem" for years. This came as no big surprise when McQueary showed up at his house. They just wanted to keep it internal. But where that train becomes a train wreck is when more kids are violated while they play good ole yankee boyz politics.
Now Franco Harris and Koo Koo Puff are leading the charge to get him off from the little slap on the wrist he has already rec'd. KKP surprises me and may be BSing-- Franco has been hit on the head too many times.
