  12-27. The following diagram shows only connectivity between persons:

  AAA BBB CCC

  12-28. The analyst can easily determine from the diagram that Alpha knows
  Bravo, Bravo knows Charlie and Delta. Bravo is suspected of knowing Echo
  and Charlie knows Delta, Bravo, and Echo. Although the same information
  could be shown on a matrix, it is easier to understand when depicted on a
  link analysis diagram. As situations or investigations become more complex,
  the ease in understanding a link analysis diagram becomes more apparent.
  In almost all cases, the available information is first depicted and analyzed
  on both types of matrices, which are then used to construct a link analysis
  diagram for further analysis.
  12-29. Link analysis diagrams can show organizations, membership within
  the organization, action teams or cells, or participants in an event. Since each
  individual depicted on a link analysis diagram can be shown only once, and
  some individuals may belong to more than one organization or take part in
  more than one event, squares or rectangles representing non-personal
  entities may have to overlap. The following illustration demonstrates that
  Ralph and Fred are both members of the "Red Fighters," and that Fred also
  is a member of the "Students for Peace." Further, since Ralph and Fred are
  shown in the same “box,” it is a given that they are mutually associated.

  12-30. There is more to overlapping organizations than is immediately
  obvious. At first glance, the overlap indicates only that an individual may
  belong to more than one organization or has taken part in multiple activities.
  Further study and analysis would reveal connections between organizations,
  connections between events, or connections between organizations and
  events, either directly or through persons. The above diagram reveals a more
