The sad story of the Davis-Besse scapegoat draws to a close. He was at the lowest level of management, where the good scapegoats are to be found, since nobody cares about them. It's far harder to try and scape a worker, since they have unions, and other workers will rally around them. Better to go after hated management.
More interesting is the fine art of setting up the scapegoat. Management doesn't have any protection, so when the big whigs say "Lie, or we'll kill you.", they can really do it. In this case, there were millions of dollars at stake, in running things a bit longer. Did the goat get these millions of dollars? I think not.
That's why everything done in management is verbal. There's always a lot of screaming and intimidation. The abusers are themselves abused. I haven't seen too many of these guys live to a ripe old age.
