I really don't consider the NSA to be law enforcement. What, if any, US laws are they responsible for enforcing? The FBI, Secret Service, Highway Patrol, city, state and country police departments, sheriffs, etc. are all in charge of enforcing laws. The NSA and the CIA as far as I can tell are not. Additionally neither are really tasked with domestic operations of any kind. National domestic law enforcement issues fall under the jurisdiction of the FBI.
