SEX RING COVERUP.
Consider this hypothetical. Your son went to a Sandusky camp, he took him to the PSU football facilities as a special treat (what kid wouldn't want to go there). While there they played some ball or whatever, wrestled and then showered together. This occurred in 2004. Now the grand jury report comes out and your son comes to you and says that he was a victim and he was raped by Sandusky. How would you feel about Paterno now knowing that he had it in his power to stop Sandusky and didn't?
He didn't report it to outside authorities. THAT is why he deserves criticism.
This is what we know for certain.
He didn't 'enable' pedophelia, as you imply. You should be more careful making such charges.
