Let's hope so, but so far the only ones arrested in this whole scandal have only Trump associates.
To me, the only true solution is to appoint a non-DOJ person to investigate potential crimes by the DOJ. At least that's the best chance we'll get an honest result, and not a cover up.
But if that doesn't happen, firing Rosenstein (or Sessions) is politically more palatable than firing Mueller directly.

One name comes to mind for SpecInv: Mr. Donald Rumsfeld. He should fit fine for such a short-term appointment.
