and, obviously, that's different from just showering. We don't know what JoePa was told. Before he died, he said he was told Sandusky was in the shower with kids and inappropriate things were going on (or something like that). McQueary says he told JoePa more. Who was telling the truth? I don't know.
Here's a hypothetical that isn't so hard for me to believe:
McQueary comes to JoePa and tells him Sandusky was in the shower with kids doing inappropriate things, but he doesn't go into detail.
JoePa thinks to himself (or doesn't even think): Nothing terribly alarming about being in the shower with the kid. (Again, that's different from what someone born in 1980 would think). Maybe JoePa thinks Sandusky was wrestling or playing around and he thinks to himself that it's probably not appropriate, especially in the modern environment, but it isn't criminal. And JoePa decides to let it go.
Do I think that's what happened? Probably not. But I don't know.
