The initiation in criminal activities is, typically, a young phenomenon. The study of the determinants of entry into criminal activities should pay attention to major events affecting youth. In many countries, one of these important events is mandatory participation in military service. The objective of this study is to estimate the causal relationship between mandatory participation in military service and crime. The authors exploit the random assignment through a draft lottery of young men to conscription in Argentina to identify this causal effect. Their results suggest that participation in military service increased the likelihood of developing a criminal record in adulthood (in particular, for property and weapon-related crimes).

The practice of using children to participate in conflict has become a defining characteristic of 21st century warfare and is the most recent addition to the canon of international war crimes. This text examines the development of this crime of recruiting, conscripting or using children for participation in armed conflict, from human rights principle to fully fledged war crime, prosecuted at the International Criminal Court. The background and reasons for the growing use of children in armed conflict are analysed, before discussing the origins of the crime in international humanitarian law and human rights law treaties, including the Convention on the Rights of the Child and its Optional Protocol. Specific focus is paid to the jurisprudence of the Special Court for Sierra Leone and the International Criminal Court in developing and expanding the elements of the crime, the modes of ascribing liability to perpetrators and the defences of mistake and negligence. The question of how the courts addressed issues of cultural sensitivity, notably in terms of the liability of children, is also addressed.
