On first glance, it appears James Comey is the leader of the FBI's effort to let Hillary get away with her crimes. Not only did he decline to recommend her prosecution when the evidence clearly showed she was guilty of multiple felonies (although not as many as we know about now), but the more we learn about the FBI's investigative processes in the case - particularly the bizarre manner in which they interviewed Hillary herself - it seems obvious that this whole thing was a setup designed to have the FBI go through the motions with no real intention of getting to the truth or acting on it.
That indicts Comey pretty badly.
