NSA Spying Not Cheap or Effective In Terrorism Fight

Spying on the whole world doesn't come cheap, but the actual figures - as with much else in the field of intelligence - are top secret.

Yet sources say terrorist detection methods only involve NSA surveillance 7.5 percent of the time. RT's Gayane Chichakyan looks into the agency's effectiveness.
