Re: Makes sense
Due process is a big thing in the court system. If it comes out that the FBI used this information in prosecutions without a Warrant, and having lied under oath, hundreds of court cases could be thrown out.
That is assuming that they tell the truth about the source of the information during the court case. It has already been demonstrated that they are prepared to lie to judges and congress so why would you assume they would tell the truth in the court case?
