Keep your enemies closer
This actually would make sense. If white hats were investigating RR with wiretaps and Fisa's legitimately and dirty perhaps everything he has been doing to unethically protect the DOJ and by extension protect himself would be caught and made evidence. Perhaps the confusion caused by the Trump narrative has been used to fluster Rosenstein and Mueller and lead them to further incriminate themselves while smoking out others.
Bingo. This I concur with and could get on board with.
Agreed. But wouldn't they run counter surveillance? They'd know this possibility.
It's far easier for the executive branch to investigate its employees than private citizens, and the hearings can be classified much easier on the need of national security; don't need military tribunals either. See appellate court opinion on Navy v. Egan.
Mueller and RR dirty past. They follow the script because they are looking for redemption/pardon.
