  taping is legal. Taped information can also be seriously affected by
  ambient noise and the relative positioning of the source and collector to
  the microphone. Writing a report based on a taped session can be
  extremely time consuming, since it takes as long to listen to a tape as it
  took to record it. This drawback can be reduced somewhat through the
  use of voice activated recording devices. Exclusive dependence on
  audiotapes tends to make the collector less attentive and more likely to
  miss follow-up questions. Also, if the tape is lost or damaged or does
  not function properly, the collector has no backup.
  • Video recording: Video recording is possibly the most accurate method
  of recording a questioning session since it records not only the voices
  but also can be examined for details of body language and source and
  collector interaction. It is also the most resource intensive requiring
  proper lighting, cameras, viewing equipment, and possibly trained
  operators. If done overtly, video recording can be by far the most
  inhibiting to the source. Even if the source is willing to be videotaped,
  there is a tendency for both the source and the collector to “play to the
  camera,” creating an artificiality to the questioning. Consult your legal
  advisor to determine the legality of overt or covert videotaping.
  QUESTIONING WITH AN ANALYST OR A TECHNICAL EXPERT
  9-30. The HUMINT collector may often find himself in the position where he
  needs to use an analyst or a technical expert, or both, in order to conduct
  questioning. Many of the techniques involved in using an analyst or technical
  expert are the same as those with using an interpreter (see Chapter 11). The
  HUMINT collector must pre-brief these supporting personnel. The degree to
  which the analyst or technical expert is involved in the actual questioning is
  dependent on the established relationship between the analyst or technical
  expert and the HUMINT collector. The HUMINT collector will always
  remain in charge of the questioning, be present throughout the questioning,
  and ensure that the questioning follows his questioning plan. He must
  ensure that the supporting analyst or technical expert has the proper
  security clearance.
  9-31. An analyst or technical expert can participate in the questioning to
  various degrees listed below from least intrusive to most intrusive. As the
  degree of participation by the analyst or technical expert increases, the
  technical fidelity of the information collected usually increases but the
  rapport between the HUMINT collector and the source decreases as does the
  HUMINT collector’s ability to control the content and judge the truthfulness
  of the information. The analyst or technical expert may provide—
  • Advice Only: The HUMINT collector does the questioning. The expert
  provides information prior to the meeting and may review the collected
  information after the meeting. The technical expert is not present at
  the actual questioning.
  • Remote Support: The HUMINT collector does the questioning. In
  addition to the above, the expert monitors the questioning and
  provides input to the HUMINT collector after the questioning as
  required. Based on the technological support, this can involve the
  expert sitting in on, but not participating in the questioning (which
