The FBI has the "Woods protocol" that supposedly prohibits presenting FISC with unverified statements. The FBI should have never filed the warrant application. FBI set up FISC as a patsy. FBI is expert at setting up patsies, it's what they do best.
So true. The issue I see with this is, the FBI lied by omission to the FISC and those involved should be prosecuted. Clearly an abuse of the court and the only way the FISC could ever regain the trust the American people have put into it is to remove the judge (followed by possible criminal charges) and prosecute the FBI agents involved with the FISA request.
