If the stockholders didn't make the decision to defraud the FAA, then why would they be on the hook for this?
Of course, i am in the camp of changing the regulation such that outcomes that would be considered gross neglegence leading to loss of life is layed on the management, regardless of whether the decision is diffused or not. Aka, they hold the statutory responsibility, and is criminally liable - that's the price of being in management. They would get the tools as management to put in place preventative measures, which can be used to cover their ass.
