I myself do not know what precisely to think. Having been at the top of the Washington hierarchy for a quarter century, I have seen many mistaken judgments. At one time I had subpoena power over the CIA and was able to inform President Reagan that the CIA had misled him. He took note and proceeded with his policy of ending the Cold War with the Soviets. On other issues I have been mistaken, because I assumed that there was more integrity in government than actually exists.
However, FBI director Comey did not need to reopen the case against Hillary simply because some new incriminating emails appeared. Having dismissed the other incriminating evidence, these emails could have passed unremarked.
