  laws, regulations, and agreements will be contingent on a detained
  source’s cooperation. An incentive for cooperation is viable only if the
  HUMINT collector has or is perceived to have the authority to
  withhold the incentive if the source is not cooperative. A HUMINT
  collector cannot promise an EPW that he will be treated in accordance
  with the GPW if he cooperates. This statement implies that the EPW
  will not be treated properly if he does not cooperate. Since the EPW
  must be treated in accordance with the GPW whether he cooperates or
  not, the HUMINT collector will rapidly lose credibility.
  EMOTIONAL APPROACHES
  8-23. (Interrogation and Other MSO) Emotional approaches are centered on
  how the source views himself and his interrelationships with others. Through
  source observation and initial questioning, the HUMINT collector can often
  identify dominant emotions that motivate the EPW/detainee. The motivating
  emotion may be greed, love, hate, revenge, or others. The emotion may be
  directed inward (feelings of pride or helplessness) or outward (love of family).
  The HUMINT collector employs verbal and emotional ruses in applying
  pressure to the source’s dominant emotions. He then links the satisfaction of
  these emotions to the source’s cooperation. Often, the presentation of like
  experiences and presenting the source with an opportunity to express his
  emotions is sufficient to result in cooperation. However, sometimes the
  source must be presented with a specific action or tangible manifestation of
  support.
  8-24. Although the emotion is the key factor, an emotional approach is
  normally worthless without an attached incentive. The incentive must meet
  the criteria listed above for the incentive approach to ensure that the
  incentive is believable and attainable. For example, this technique can be
  used on the EPW/detainee who has a great love for his unit and fellow
  soldiers. Simply having the source express this emotion is not enough. After
  the source expresses this emotion, the HUMINT collector can take advantage
  of this by telling the EPW/detainee that by providing pertinent information,
  he may shorten the war or battle in progress and save many of his comrades'
  lives, but his refusal to talk may cause their deaths. This gives the source the
  alternatives of facing the status quo or expressing love of comrades through
  cooperating with the HUMINT collector.
  8-25. Religion is an especially difficult topic to use in any emotional
  approach. An approach using religion may encourage the source to be further
  motivated by love, remorse, futility, or even pride to cooperate with the
  interrogator. On the other hand, an approach using religion may also
  encourage the source to end any rapport and cooperation with the
  interrogator. Although it is acceptable to use religion in all interrogation
  approaches, even to express doubts about a religion, an interrogator is not
  permitted to denigrate a religion’s symbols (for example, a Koran, prayer rug,
  icon, or religious statue) or violate a religion’s tenets, except where
  appropriate for health, safety, and security reasons. Supervisors should
  carefully consider the experience level of their subordinates before permitting
  the use of religion in any interrogation approach.
