  maturity and judgment who are totally knowledgeable of the collection
  requirements and able to make well-reasoned decisions based on limited
  information. Collection (interrogation, debriefing, and elicitation) can be
  integrated into screening activities; however, it slows the screening process
  and decreases the number of potential sources that can be screened.
  6-4. Human source screening is the evaluation of an individual or a group of
  individuals to determine their potential to answer collection requirements or
  to identify individuals who match a predetermined source profile. The
  purpose of screening is to––
  • Identify those select individuals among the target audience who have
  information of potential value and who are willing or can be persuaded
  to cooperate.
  • Identify individuals who match certain criteria that indicate them as
  being potential subjects for source operations or matching the profile
  for collection by special interest groups such as TECHINT or CI.
  6-5. Screening requires the development of criteria that are indicators of
  potential information. These might include rank, position, gender, ethnic
  group, appearance, and location.
  6-6. Screening is an integral part to all HUMINT collection operations.
  While questioning an individual source, a HUMINT collector may switch
  between screening (finding out general source areas of knowledge) to
  interrogation, debriefing, or elicitation (finding out detailed information
  about a specific topic). In operations, such as EPW or refugee operations that
  involve large numbers of potential sources, screening will normally be
  conducted as a separate but collocated operation as part of the overall
  interrogation or debriefing effort. The high number of potential sources being
  dealt with in most human source screening operations requires a systematic
  approach be developed and utilized to make the most effective use of the
  personnel and resources being allocated to the source screening operation.
  SCREENING OPERATIONS
  6-7. Like all intelligence operations, human source screening operations are
  focused on certain targets. Although the exact target population group will
  depend on the requirements of the theater of operations, the target focus of
  source screening operations is best described as the permanent and
  transitory population in the AO. This definition includes local indigenous
  populations, refugees, and travelers in the area, and detainees (including
  EPWs). Specifically excluded from this definition are members of the HN
  forces (military and paramilitary), members of allied forces, and members of
  HN government agencies who are available to US forces through liaison
  operations. Other personnel not indigenous to the AO (such as legitimate
  NGOs, humanitarian organizations, UN personnel) are available to US forces
  for voluntary debriefing and should be excluded from screening operations.
  6-8. Screening operations may be conducted in a variety of situations and are
  dependent on the operational situation and the population. Although every
  source screening operation has the same basic purpose, each can be directed
  against different segments of the population in different locations throughout
