Well, I guess it’s ok, then. Paterno told his boss. It’s not like this was a serious matter . . . only the minimum effort was necessary. Besides, Sandusky was his buddy. /s
It hardly ever is enforced nowadays but there is a crime of "misprision of a felony" which might have been applicable here if it could have been proven that any witness knew (not suspected, not had heard or any other mush) that a felony had actually been committed by a known individual. Everyone KNEW Sandusky but, on what evidence there was at the time of the crimes, no one but Sandusky and his victims actually SAW his crimes. McQueary and the janitor are both verrrry flawed witnesses. No one wanted to pursue anyone else which might have brought forth more evidence against who knows whom? But, you know, there are people who agree with the Keith Olberman approach and its simplicity.
