> Between 2001 and 2012, the FISA judges approved 20,909 surveillance and property search warrants - an average of 33 a week. During that 12-year period, the judges denied just 10 applications. Prosecutors withdrew another 26 applications.
> From 2007 to 2012, FISA judges also approved 532 "business record" warrant applications, the category used in the order that directed Verizon to release metadata on all phone calls inside the United States. No business record warrants were rejected.
and, on the judges perception of themselves:
> Walton, the senior judge on FISA, declined to be interviewed. In a statement, he said: "The perception that the court is a rubber stamp is absolutely false. There is a rigorous review process of applications submitted by the executive branch, spearheaded initially by five judicial branch lawyers who are national security experts, and then by the judges, to ensure that the court's authorizations comport with what the applicable statutes authorize."
