This is some pretty damning stuff. I can only be suspicious that Freeh was really working for Corbett or anyone wishing to continue to scapegoat the PSU administrators and coach Paterno. It wouldn't surprise me if some current board members are complicit in the hiring of Freeh for such purposes.
The only other explaination is that Freeh is a not very good at this stuff, which is also plausable given his track record. Either way it stinks, and the damage has been done. Hope this critique gets some media traction.
