Does McQueary's e-mail this week put the microscope on him instead of JoePa?

Was just thinking that everyone has been crucifying JoePa based on McQueary's testimony, but McQueary is trying to clear his name by saying he stopped it and told the cops and that appears to be a lie....could he have lied about what he told JoePa? What if his dad convinced him that maybe he didn't see what he thought he saw and encouraged him to water-down what he saw to JoePa? What if JoePa didn't hear that Sandusky was raping the kid but instead there was some kind of inappropriate behavior going on? What if when Curley and Schultz weren't told the whole truth by McQueary in their discussion a week later?

I have a feeling that Schultz and Curley's attorneys are going to be able to find a bunch of holes in McQueary's testimony...could blow the whole thing up and help call into question whether or not JoePa, Curley and Schultz heard the truth about what happened.
