The PA mandated reporter law is pretty poorly written in my opinion. From a strict reading of it, Paterno had NO LEGAL OBLIGATION to report this to the police (in fact, nobody has to report it. There are two reasons for this. First off, the child wasn't in Paterno's care or being dealt with in his employed capacity. Second, the mandated report is to be made to the "... person in charge of the institution, school facility or agency..."
That is why he wasn't charged criminally.
Even the two lying weasel administrators may be able to get off the hook with that legalese argument. In 2002, Sandusky was not in their employ and neither did the kids 'come before them' or wer even part of any formal penn state program.
Do you think that makes any of this right ?
