A community interview is one of the most important and fundamental methods of acquiring information in the work of a detective. One may say that a community interview precedes or finishes an operation, irrespective of whether we are interested in the past of a potential life-time partner, business partner, employer, employee or contracting party, or another person who at a given moment raises doubt or anxiety. During a community interview, we make use of all resources available (people and state-of-the-art technology). As an addition to direct observations, a community interview allows working out a complete and credible profile of the observed person.
