How can you tell if knowledge of a scandal (or 3 or 4 scandals for that matter) goes all the way to the top? It's easy. No one gets fired, because firing is the only sure way of making people talk. To think something is 'OUTRAGEOUS' is admitting that you don't really want to find out what happened. To fire someone, knowing they'll begin talking as soon as you fire them, is to be serious about finding the answer.
I doubt anyone will lose their jobs. Just reassigned to a higher paying position.
