If you are talking about the 2002 case, he was told about that. There does not appear to be any more cases that involved the football team's facilities after that. The abuse uncovered in the 2008 case that blew the lid off this occurred off campus mostly at Sandusky's home.
Then, in 2000, a janitor caught Sandusky orally sodomizing a boy in the Penn State football locker room showers but was too afraid to report it to police. Why was he afraid? Afraid of Sandusky? Afraid to bring shame on Penn State? Afraid because Sandusky had been Joe Paterno's good friend for 30+ years?
Or maybe he was just afraid of getting involved. The other janitors told him to report it. They didn't seem concerned about Paterno's reaction.
The expressed their concern to him that they might lose their jobs if he reported it. He told his supervisor. His supervisor gave him a name of someone to report it to. It was never reported.
His coworkers express to him their fear of being fired if he reported it.
Well, we know that Sandusky still had an office in the Athletic building until Sunday (at least, he was still in the campus directory) and had access to the athletic building - even if perhaps keys to the showers were taken away. We know he was hosting sleepover camps at a Penn State facility through 2008.
We know that the GJ documents we are reading list eight victims, but by last night authorities had identified twenty.
We know that Curley told that GJ that there was no way of policing Sandusky bringing boys on campus after 2002.
Let's see if any of the additional twelve . . . or any more to surface . . . involve Penn State property, like the weight room. And let's wonder about all of the boys since 2002 that we don't know about, and who wouldn't have been around Sandusky had everyone done the moral thing and some not just the "I did the bare minimum i was required to do legally, so don't look at me" things.
I don't think we're remotely in the clear to say nothing happened after 2002.
