There is one prepatory step that will apparently never occur to them: admit they have done wrong, identify the people they have wronged, make it right by giving them full compensation, and document that they have done so.
That's a sucker's bet. These people are PROFESSIONALS. They'll go with the tried-and-true method and round up some scapegoats, of course.
A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects.
-Heinlein, Time Enough For Love
No amount of careful planning will ever replace dumb luck.
