  explains that the actions of the first HUMINT collector were largely the
  result of an inferior intellect and lack of sensitivity. The inference is that the
  second HUMINT collector and the source share a high degree of intelligence
  and sensitivity.
  8-67. The source is normally inclined to have a feeling of gratitude towards
  the second HUMINT collector, who continues to show sympathy in an effort
  to increase rapport and control for the questioning that will follow. If the
  source’s cooperation begins to fade, the second HUMINT collector can hint
  that he is a busy person of high rank, and therefore cannot afford to waste
  time on an uncooperative source. He can broadly imply that the first
  HUMINT collector might return to continue the questioning. The Mutt and
  Jeff approach may be effective when orchestrated with Pride and Ego Up and
  Down, Fear Up and Down, Futility, or Emotional Love or Hate.
  8-68. Oversight Considerations: Planned use of the Mutt and Jeff
  approach must be approved by the first O-6 in the interrogator’s chain of
  command. The HUMINT collector must include as a part of the interrogation
  plan—
  • No violence, threats, or impermissible or unlawful physical contact.
  • No threatening the removal of protections afforded by law.
  • Regular monitoring of the interrogation shall be performed by
  interrogation personnel.
  8-69. False Flag. (Interrogation) The goal of this technique is to convince
  the detainee that individuals from a country other than the United States
  are interrogating him, and trick the detainee into cooperating with US forces.
  For example, using an interrogator who speaks with a particular accent,
  making the detainee believe that he is actually talking to representatives
  from a different country, such as a country that is friendly to the detainee’s
  country or organization. The False Flag approach may be effectively
  orchestrated with the Fear Down approach and the Pride and Ego Up.
  8-70. Oversight Considerations: The interrogation chain of command
  must coordinate an interrogation plan that uses the False Flag approach
  with the legal representative and the 2X, and receive approval from the first
  O-6 in the interrogator’s chain of command for each specific use of the False
  Flag approach.
  • The use of the False Flag approach must complement the overall
  interrogation strategy and other approach techniques listed in the
  interrogation plan.
  • When a HUMINT collector intends to pose as a national of a third-
  party country, that country must be identified in the interrogation
  plan.
  • No implied or explicit threats that non-cooperation will result in harsh
  interrogation by non-US entities.
  • HUMINT collectors will not pose or portray themselves as any person
  prohibited by this manual, paragraphs 8-10 and 8-11 (for example, an
  ICRC representative).
