On that count, they are almost certainly going to be found correct. The FBI can have probable cause ten times over, enough evidence to make a slam dunk case, and it still does not issue any recommendation to the prosecutor.
-- Why is Comey staging this press conference? --
To further politicize the law. As you know, the results of FBI investigations are "secret" from the FBIs point of view.
An interesting development, just the same. We'll know in a few hours, what the man had to say.
Comey is compromised because his boss is compromised. It’s so obvious. Let a grand jury decide. That’s the only honest course of action.
I suspect that Lynch forced him to have this press conference. She won't show up this time as she has on other occasions. This is all about reassuring the public that the FBI is not politicized. Wink, wink.
