How Could NSA Have Stopped 9/11 Disaster?

Dear Rep. McCaul and Sen. Carper,
The National Security Agency's (NSA) continued confiscation of American citizen's phone records is clearly violates the Fourth Amendmen to the Constitution, regarding unreasonable searches and seizures. In spite of that, there is a continued drumbeat to allow the NSA to continue its unconstitutional operation, presumably on the basis that a mechanism for control of terrorism is more important than individual citizen rights. Notice that this is socialism versus democracy.
Rep. Peter T. King of New York now makes the general claim that if the NSA had been in operation prior to the 9/11 disaster involving the downing of the two New York towers, that disaster have been avoided. In effect, Peter King is saying that we must continue to ignore NSA's violation of the Fourth Amendment to the Constitution to avoid future disasters.
The thing that's a little sickening about this statement is that it is all too common, wherein a person of supposed authority makes a general statement lacking specific details to support his position. Because Peter King is a Representative of the federal government from the state of New York, is that a reason that I should take him at face value no matter what he says?
I want to know how operation of the NSA in its present form could have avoided the 9/11 disaster. Peter King is obligated to supply that information, to support his general claim.
