A crime was committed on the campus of Penn State, witnessed by a grad assistant. The grad assistant, not completely trained and educated on proper procedures, reports the crime to his immediate supervisor. Next step - said supervisor calls the police, because this was a CRIME. This was not some stupid NCAA rules violation, and you don't get a free pass because you reported it to the A.D. If the grad assistant had witnessed a theft, someone spray painting the walls, committing vandalism, etc., no one would be questioning what should be done.
