According to more infallible sports journalism McQueary claims he stopped the 2002 shower incident. Here's the excerpt from the ESPN article, which also points out that it's not clear how detailed and descriptive McQueary's report to Paterno, Curley and Schulz was. All along I've been trying to explain to people, even fellow lawyers, that the grand jury presentment isn't a summary of proven facts, but a summary (not even verbatim) of testimony (not necessarily corroborated). Thus, drawing conclusions about failures in moral responsibility based on the wording is, without a doubt, the stupidest and most dangerous form of willful ignorance by reporters who should know better than to tell the public, "See, here's what someone did or didn't do."
Wide receivers coach Mike McQueary told a grand jury that in March 2001 when he was a graduate assistant, he saw Sandusky attacking a boy about 10 years old in a shower at the Nittany Lions' practice center. McQueary did not go to police but instead told Paterno, Curley and Schultz, although it is unclear how detailed a description he gave. Schultz, in turn, notified Spanier.
