In a broad sense, international criminology can be described as the set of activities related to crime prevention and control, coming from the academia, public and private institutions and agencies, to join efforts to debate and publish and make policies, addressed to a global audience beyond a single country. This process of internationalization of criminology, started since its beginnings as a science, at the end of the 19th century through important congresses and meetings developed in Europe, where public officials and academics met. In the 21st century we can talk of a global or globalized criminology around the world, expressed also via websites on the Internet. Together with international crimes (genocide, crimes against humanity, crimes of war and, to a lesser extent, aggression as crime against peace), transnational crimes (corruption, financial crime, terrorism, organized crime, and its different modalities of illegal trafficking, cyber-attacks, and crimes against the environment), as well as crimes of abuse of (political and economic) power (enforced disappearances, summary executions, torture) are the subject matter of international criminology. However, the concept of international criminology is elastic and welcomes any international approach to other topics, traditionally thought domestically; in any case from the international perspective the social-political dimension of criminality appears as a much more relevant issue than the criminal’s personality (and treatment) and protection of victims and the international community become the focus of interest.
Within the internationalization of criminology there are at least two trends that deserve further analysis. The first one is how to balance the cultural differences among all the countries and the myriad of interests involved in the construction of an international criminology. Some criticism is heard in the sense that international criminology is influenced by American or Anglo-Saxon views. From this perspective it is observed a risk of producing academic, legal, and policy criminological transplants without considering the cultural and socioeconomic context of every country and the voices of their inhabitants, very diversed in themselves. The second trend refers to the role of international criminology in relation with the increasingly diffuse borders between police, intelligence agencies, and military forces; crime control and war; or internal and external security, particularly if cyberspace beyond borders is considered. Even though international crimes have always been a core topic, war and political and economic abuse of power across borders, mainly conceived as state and corporate crime, have been quite forgotten in the agendas of both national and international criminology. Today there are different forms of cooperation among countries in conflict situations, (e.g., terrorism, border controls, and the so-called refugee crisis) where the military, intelligence agencies, police forces, and private corporations of different countries work together, providing international criminology new topics for critical reflection and action.
