On the off-chance that a "journalist" is lurking in this thread, I'll spell out for you what the above post implies.
In order for Joe Paterno to have "done more" in this situation, he would have had to do both of the following:
1) Know Mike McQueary, the witness of the shower incident, better than Mike's own father knows him in order for Joe to be able to interpret the vague report as something much more than Mike was verbalizing, and then
2) Recognize & interpret that the "something much more" was actually child sexual victimization, which the trained mandated reporter was unable to do.
Those who think Joe Paterno possessed capabilities such as these would do well to familiarize themselves with
one of the chief criticisms of Penn Staters.
