I agree. Im just pointing out that I dont think there are amy criminal cases where FISA evidence was used to get a conviction.
i was agreeing with you
But that’s kinda the point and I don’t have a cogent argument for you but the FBI uses a process called parallel construction where they develope two lines of evidence one that was obtained legally but in reality is cherry picked or augmented some sort of evidence gained Via illegal surveillance or other shenanigans , the parallel track, that FBI hides from the discovery process. Any case they had fisa warrants most likely has this augmented parallel track. Apologies for the ad hoc nomenclature to describe poorly their scam
The way it works is the FISA phone, email, text etc. intercepts are used to get the names of potential players and info that they can then claim they acquired the info through proper methods.
FISA was used to commit criminal acts.
