(Oh, you mean the "halfback" -- Paterno's supervisor -- IMMEDIATELY went to the authorities, eh??? Yeah, right)
He did. He reported it to Tim Curley, the PSU AD, who went to Gary Schulz, PSU VP who oversaw the PSU Police Department, and both of them went to the Pres of PSU about the matter.
What more was Paterno supposed to do. It got to the top and got there rather quickly with a sense of urgency.
