Did Joe Pa know? Based on the multiple accounts from Mike McQueary that proved to be wholly unreliable, there's no proof that Joe Pa knew kids were being abused, just as the Second Mile people didn't know, the State Police didn't know, the State's Attorney's didn't know, the agency that approves adoptions in Pennsylvania didn't know . . . See a trend?
Since McQueary's version of events changed repeatedly, it's impossible to know what he told JP, but we do know MM was so concerned about what he saw that he left the facility and went to his dad's house. He didn't try to help the kid, apprehend Sandusky, call the cops, nothing. He just left. And neither he, his father, nor their family friend were concerned enough to call the cops, either. So, an eyewitness thought so little of what he saw that he left, only giving JP a vague report of it the next day, but JP should've done something more than inform his superiors (which he did)?
Again, multiple public and private agencies, each trained to spot child abusers and abuse, didn't catch Sandusky, but the coach who couldn't even remember his player's names, who witnessed nothing, and who was given what can generously be characterized as a far less than credible story, should've known and acted?
As for Louis Freeh, his hastily assembled report was reminiscent of a high school book report, replete with both factual errors as well as grammatical ones. It was roundly discredited by Dick Thornbirgh's far more thorough analysis, and Freeh quickly went quiet rather than defend a document unworthy of his previous government work and reputation.
As I said, you get dumber with every post.
