Some group-focused models attempt to categorize the structural aspects of organized crime. Others focus on the nature of membership of the group. Still others consider the internal dynamics of groups and their relationship to the surrounding environment. Organized crime can be considered from many different vantage points, using models derived from a wide variety of disciplines. The article offers a framework for considering the wide range of questions posed by the phenomenon of organized crime. The framework provides a context within which group-focused and activity-focused models can interrelate, taking account of such other factors as context, ultimate impact, and policy response. The “why” and the “how” questions can often be illuminated through the use of economic tools and political analysis, which can also shine light on the “who” question. In the law enforcement policy context, awareness of the variety of models is vital, because all policymaking is based on sets of assumptions that are often not made transparent. Figures, notes
