You're right. Nothing will come out of this. It is very important for these companies that they are sued now by the super-friendly administration and be gently punished (Punishment: Don't do it again, Ok? Defendents: We promise we won't do it again) or settled for a measly sum of a few million (no admission of guilt).
Then you can be never tried again for the same crimes. There is some law against being tried for the same crimes multiple times.
