This volume is devoted to the dark side of human mobility, that is migrant smuggling, and, linked with it, human trafficking. Both subjects will be mainly treated from an Italian perspective; however, due to their having a generally transnational character, the analysis will necessarily require that international and supranational actions/measures also be taken into account. Moreover, the legal perspective will be supplemented by the phenomenological/criminological one, through which the authors try to provide the work with a realistic dimension aimed at grasping the practical aspects of both migrant smuggling and human trafficking emerging from the different ways in which such crimes are de facto committed.
