Here's my take. Joe knew there was a problem and he told someone. When no one did anything about Sandusky Joe should've done more. He didn't and that's on him. But if any of a half dozen to a dozen officials, WHOSE JOB IT WAS TO DEAL WITH SUCH THINGS, had done their job, Joe would have not been in that position.
To Joe, I say RIP. To the police and psu suits that failed to protect those kids and contributed to the downfall of a great coach and a good man, they can rot in hell.
It is JoPa's fault we ever arrived at the McQueery/shower scene. The child rape did not begin that day!
