The FBI investigation provides plenty of ammunition for the election. It makes it crystal clear that Hillary Clinton lied about not sending classified emails. But it also states that it isn't going to do a thing about it.
Here's Comey trying to sum up the classified email abuses
FBI investigators have also read all of the approximately 30,000 e-mails provided by Secretary Clinton to the State Department in December 2014. Where an e-mail was assessed as possibly containing classified information, the FBI referred the e-mail to any U.S. government agency that was a likely “owner” of information in the e-mail, so that agency could make a determination as to whether the e-mail contained classified information at the time it was sent or received, or whether there was reason to classify the e-mail now, even if its content was not classified at the time it was sent (that is the process sometimes referred to as “up-classifying”).
From the group of 30,000 e-mails returned to the State Department, 110 e-mails in 52 e-mail chains have been determined by the owning agency to contain classified information at the time they were sent or received. Eight of those chains contained information that was Top Secret at the time they were sent; 36 chains contained Secret information at the time; and eight contained Confidential information, which is the lowest level of classification. Separate from those, about 2,000 additional e-mails were “up-classified” to make them Confidential; the information in those had not been classified at the time the e-mails were sent.
The FBI also discovered several thousand work-related e-mails that were not in the group of 30,000 that were returned by Secretary Clinton to State in 2014. We found those additional e-mails in a variety of ways. Some had been deleted over the years and we found traces of them on devices that supported or were connected to the private e-mail domain. Others we found by reviewing the archived government e-mail accounts of people who had been government employees at the same time as Secretary Clinton, including high-ranking officials at other agencies, people with whom a Secretary of State might naturally correspond.
This helped us recover work-related e-mails that were not among the 30,000 produced to State. Still others we recovered from the laborious review of the millions of e-mail fragments dumped into the slack space of the server decommissioned in 2013.
With respect to the thousands of e-mails we found that were not among those produced to State, agencies have concluded that three of those were classified at the time they were sent or received, one at the Secret level and two at the Confidential level. There were no additional Top Secret e-mails found. Finally, none of those we found have since been “up-classified.”
Although we did not find clear evidence that Secretary Clinton or her colleagues intended to violate laws governing the handling of classified information, there is evidence that they were extremely careless in their handling of very sensitive, highly classified information.
For example, seven e-mail chains concern matters that were classified at the Top Secret/Special Access Program level when they were sent and received. These chains involved Secretary Clinton both sending e-mails about those matters and receiving e-mails from others about the same matters. There is evidence to support a conclusion that any reasonable person in Secretary Clinton’s position, or in the position of those government employees with whom she was corresponding about these matters, should have known that an unclassified system was no place for that conversation. In addition to this highly sensitive information, we also found information that was properly classified as Secret by the U.S. Intelligence Community at the time it was discussed on e-mail (that is, excluding the later “up-classified” e-mails).
None of these e-mails should have been on any kind of unclassified system, but their presence is especially concerning because all of these e-mails were housed on unclassified personal servers not even supported by full-time security staff, like those found at Departments and Agencies of the U.S. Government—or even with a commercial service like Gmail.
Separately, it is important to say something about the marking of classified information. Only a very small number of the e-mails containing classified information bore markings indicating the presence of classified information. But even if information is not marked “classified” in an e-mail, participants who know or should know that the subject matter is classified are still obligated to protect it.
The clear evidence standard is of course absurd, because Clinton and her people knew the regulations and clearly violated them. That standard would apply to any other employee, yet Hillary is allowed to act as if she had no idea of what the law was or that she was violating it.
So Comey demolishes Hillary's lies about classified emails on the one hand and then shrugs the whole thing off on the other. You can see that as the action of a man in an impossible spot who does his job demolishing the alibi and then walks away having provided the information while knowing that it can be used politically, but not criminally.
Effectively he's blown the whistle but can't do anything about it.
