With protection like that, it is no wonder Clinton was never worried about being indicted.
In fact, The New American reported in October 2016 that a heavily redacted FBI document from August 2015 mentions a group called “The Shadow Government” — made up “of very high-ranking STATE officials” — that was working to protect Clinton. So, Comey’s decision to protect Clinton did not happen in a vacuum. He may have been following “guidance” (if not a direct order) from those higher than him on the totem pole.
