  11-23. When conducting source meetings in a public setting, a more natural
  appearance is desirable. The seating needs to conform to the norm at the
  location where the meeting is taking place. For example, if meeting at a
  restaurant, the HUMINT collector, interpreter, and source will sit naturally
  around the table.
  INTERACTIONS WITH AND CORRECTION OF THE INTERPRETER
  11-24. The HUMINT collector must control the interpreter. He must be
  professional but firm and establish that he is in charge. During a questioning
  session, the HUMINT collector corrects the interpreter if he violates any
  standards that the pre-mission briefing covered. For example, if the
  interpreter interjects his own ideas into the meeting, he must be corrected.
  Corrections should be made in a low-key manner as to not alienate the
  interpreter, interrupt the flow of the questioning, or give the source the
  impression that there is an exploitable difference of opinion between the
  HUMINT collector and the interpreter. At no time should the HUMINT
  collector rebuke the interpreter sternly or loudly while they are with the
  source. The HUMINT collector should never argue with the interpreter in the
  presence of the source. If a major correction must be made, the HUMINT
  collector should temporarily terminate the meeting and leave the site
  temporarily to make the correction. The HUMINT collector needs to
  document any difficulties as part of his interpreter evaluation. The HUMINT
  collector must always ensure that the conduct and actions of the interpreter
  are within the bounds of applicable law and policy. Applicable law and policy
  include US law; the law of war; relevant international law; relevant
  directives including DOD Directive 3115.09, “DOD Intelligence
  Interrogations, Detainee Debriefings, and Tactical Questioning”; DOD
  Directive 2310.1E, “The Department of Defense Detainee Program”; DOD
  instructions; and military execute orders including FRAGOs.
  11-25. The HUMINT collector must be alert for any signs that the
  interpreter is not performing as required. The following are some indicators
  of possible problems.
  • Long-to-short. If you take 20 seconds to express yourself and the
  interpreter reduces it to a 3-second translation, it may indicate that
  something has been omitted, and you should not proceed until you
  have resolved the issue. There is nothing wrong with stating that you
  would “prefer” the interpreter translate everything that was just said.
  If you have trained your interpreter properly, this should not be an
  issue. If it arises even with the training you have given the interpreter,
  then it has significance and you must not let it pass.
  • Short-to-long. If you take 5 seconds to express yourself and the
  interpreter expands it to a 30-second translation, it may indicate that
  something has been added, and you should not proceed until you have
  resolved the issue.
  • Body-language shift. If the interpreter’s body language suddenly has a
  significant shift from his normal behavior, you should look for the
  reason. (It is advisable for you to determine a base line of behavior for
  your interpreter to facilitate recognition of the changes.) Perhaps he is
  reluctant to translate what you just said. Be aware that the body shift
