Of course the boy was afraid. Of course the boy didn’t want to say anything out of fear and shame. That is why the adults had to step up to the plate, including the coach who actually witnessed it. Did they? We all know the answer to that. They passed it along as if it was a report that Sandusky was caught in a traffic violation.
He was probably confused why it seemed so authentically repellent and disgusting.
EVERYONE was afraid.
Having the boy open up in their office, the school officials STILL urged the mother to carefully consider the consequences before reporting anything.
Plus Sandusky most likely threatened him that something bad would happen if he told. Hard to imagine he did not threaten.
