When asked football questions that's fine.
But when you find out in 2002 that a Graduate Assistant has seen your Assistant Coach diddling a boy in the shower and you do nothing "no comment" is a little weak.
The DA in 1998 had Sandusky on tape admitting to a mother that he had been 'showering' with her son. They all knew for years. They all enabled him to keep raping. They all watched for years as he brought little boys into and out of the showers at odd hours. The guys that cleaned the showers watched.
