In the "national security" sphere, the entire system is ex parte.
Yet evidently the diminished value of both the dossier and its author were not disclosed to the judge - in January or subsequent renewals.
I get some pushback when I use expressions like "rubber-stamp FISA court".
Shepard Smith was arguing on Fox yesterday that a FISA court judge is almost like a Supreme Court justice - I was laughing so much I nearly drove off the road. In this case, almost every material fact about the "evidence" was withheld, or coyly skirted.
They're really the two choices here: either "the world's premier law enforcement agency" was manipulated by one freaky Brit spook, or "the world's premier law enforcement agency" conspired with the freaky Brit spook to manipulate the judge.
Me again from months ago: There was enough of a pseudo-dossier, by the debased standards of the bloated US 'intelligence community', to be used as a pretext to get the rubber-stamp FISA court to approve 24/7 surveillance of everyone around Trump - and maybe that would turn up something to destroy him. Every sentient creature knows that - because everyone understands that if they'd found anything they'd have leaked it.
