Crime triangle

Definition

A visual tool, also called the problem analysis triangle, showing the three routine activity elements as the sides of a triangle. An outer triangle adds controllers: handlers (who manage offenders), guardians (who protect targets), and place managers (who control settings). Used in problem-oriented policing to identify the missing controller.
