Police response to incidents of intimate partner violence can be critical. This volume investigates the elements in the institutional, legal and organizational context that are relevant for police response to incidents in the realm of the private sphere and whether there exists a relation with the reporting of such incidents by victims. Addressing this complex question requires insights from research, policy and practice and, as such, any conclusions will have implications for each of these fields. This volume addresses issues that are key elements in the relationship between the (legal) response to family violence and the reporting by victims. These issues concern societal and legal definitions of family violence employed in research, policy making and legal practice; how the legislation of various countries covers violence in the private sphere; the way the police deal with reported incidents of intimate partner violence; and the role that other interventions play in the response to and combat of family violence and intimate partner violence.
