The FISA judges must have been in on it. Otherwise, they would be referring the fraud against the court to DOJ for prosecution.
Even if the FISA judges were previously complacent or even “in on it,” the public revelation that the FISA process was abused is a mark against the judges. And — trust me on this — judges jealously guard their reputations. None of them wants to be regarded by their colleagues and the public as slow-witted or compromised and failing to protect the FISA process and Americans’ privacy against abuse. Given a chance, the FISA judges will likely act against Rosenstein and others who misled them.
There's no question about it.
At least one FISA judge has been removed...he was overseeing the Gen. Flynn case.
That same judge also happens to be 'friends' with agent Strozk.
