The study of international crimes - such as war crimes crimes against humanity and genocide - deserves to grow into a separate and fully fledged specialization within criminology called supranational criminology. Supranational criminology entails the study of international crimes behavior that shows affinity with these crimes the causes and the situations in which they are committed as well as interventions and their effectiveness. What exactly entails supranational criminology? What are international crimes? Should other forms of behavior also be qualified as international crimes? What are the specific characteristics of international crimes as forms of state sponsored or state facilitated crimes? Explanatory theories have to be developed which can be translated into testable hypotheses. Which theories from mainstream criminology can provide answers for the prevalence or causes of international crimes? Have the international courts and tribunals succeeded in their aim? This book repairs the fundamental and historical neglect of criminology and breaks out of a state of denial by putting international crimes on the criminological agenda.
