The analysis of international penal justice discourse, which is a privileged mode of social reaction to mass murders, as well as that of cruel practices by executors reveal what is not said about warring violence. Taboo manipulation, as inflicted on the body of victims by executors, implements a norm that is in contradiction with organised social reaction’s vision of man. Thus, lack of interpretative tools for such violence, including criminological ones, helps us understand what violence teaches us about our interpretative difficulties.
