Just to be clear !Rarely does an accused person admit guilt..particularly on NATIONAL NEWS.
However..a graduate student tends to be fairly intelligent....and I tend to trust him more than Sandusky when he states a 10 year old was pinned to the wall being buggered in a shower at PENN STATE!!
Sandusky did not admit to sexual misconduct, just poor judgement in that he should not have had the boys around at certain times. ie, while showering.
As to the accusation by the graduate student, Sandusky just said 'you have to ask him' when Costas questioned Sandusky on why the GS would lie ?
