Nothing involving the DA's Office and Sandusky in 1998 passes the smell test. There was a solid case, with multiple witnesses, multiple victims, an admission, and the case wasn't prosecuted. The "abuse person" in the office was removed from the case. DPW at least claims never to have received key information in the case.
Yet we know he didn't prosecute.
He was never asked about that meeting, which might be unrelated. Conversely, Schreffler might have been requested not to say anything about it to the AG, because it was related to the perjury case.
I have heard some stuff in this regard. While the 10/13/98 meeting might have been for some other purpose, that would not preclude a decision "not to prosecute if Sandusky would get help with the problem" situation.
I would not be surprised in the least if that was what happened.
