This article focuses on how a small armed band – the Scorpions – participated in the events that occurred in former Yugoslavia. Considering the role and responsibility of such small units in one of the most radical destruction of humankind is not only necessary to understand and, ultimately prevent such tragedies. It is also justified on an epistemological basis. Rather than considering such participation through the individual and motivational aspect, which is a common perspective in main stream criminology, focusing on western societies’ security preoccupations, I argue that grasping the dynamics underlying the destruction of entire populations necessitates to consider the collective and political nature of such violence, and therefore to focus on the group. Hopefully, such approach will help producing a more accurate knowledge, and thus a new look on mass crimes.
