Ana is pissed about the abuses of the FISA court enumerated in the Carter Page dustup.
I suspect that kind of thing is more normal for the FBI than abnormal and probably every single FBI director could be charged with unlawful and distasteful "citizen surveillance" during his/her tenure.
I'm not a giant fan of the FBI myself, as a general matter, independent of director or administration. They're still cops and subject to pretty much all criticisms that can be leveled at cops. I also have a more generalized beef with the federalization of crime. But I'm not going to take that out on any specific director.
That said, Comey seemed particularly a "glory guts" director that put himself or allowed himself to be put in the middle of things he'd have better stayed out of or lowered his profile. That doesn't merit criminal prosecution. Still, I find it vaguely satisfying that he's getting wrung out a little.
What will be interesting to see is whether he does the "innocent man" defense and push for a quick trial, or employ the dilatory tactics common to those that can afford them. He can probably file highly meritorious pretrial motions on things like selective prosecution, but however meritorious, those are long-shots. He's probably best off to go to trial as fast as he possibly can. ED Va is known as a rocket docket in the civil context, don't know about criminal. But this is a pretty simple case, it seems.
