Law/legal philosophy indeed is different everywhere... Where i'm at, I was always told that the primary purpose of the process is to deter and prevent the crime from ever happening again.

In this particular Boeing case, I bet my ass that the corporate world is taking notes as the plea deal is a sweet deal; thus a incentive is provided to do the crime. It would be funny if the victims of the next Boeing sue over inciting the crime they will be a victim of.
