A follow up: Sandusky got emeritus status as a result of negotiations in his retirement in 1998. So, who was involved in those negotiations, and who approved the package from the University side. The approver(s) are the enablers, because they know why he was retiring.
Paterno kept him on as Defensive Coordinater AFTER his retirement. Paterno was asked how he felt about losing Sandusky. Paterno said it was 'like a son walking out of his house'.
