The FBI shot itself in the foot with respect to the court. Why should the court trust the FBI? Why should ANYBODY trust the FBI? It won't even publicly admit it screwed up with this warrant. It defends it as righteous.
Yes, and no. The FISC was lied to and can be given a judicial pass except for the part where it is alleged that they FISC judge knew the request had political motivation. At that point he stopped being a judge and became a pundit. Once he signed the warrant with that knowledge, he committed a violation of the FISA and should be held accountable. There is no doubt in my military mind that he will be protected by the other 10 judges, but he should no longer be on the court. WRT the FBI, I concur 100%.
