The Ninth Biennial International Conference "Criminal Justice and Security - Contemporary Criminal Justice Practice and Research" (previously "Policing in Central and Eastern Europe") was a meeting of scholars, researchers, and practitioners in the field of criminal justice and security from Europe and the United States. The conference was designed as a venue for the exchange of views, concepts, and research findings with the goal of discovering common solutions for practical issues from different parts of the world. In these conference proceeding 34 peer reviewed papers are presented under 3 broad categories: 1) Policing, 2) Criminal Justice and Criminology, and 3) Security Studies. The vast majority of these papers come from countries of the former Yugoslavia and the conference has become an important "meeting point" of scholars from South-Eastern Europe. These countries share not only similar political, economic, security, and historical experiences, but are also members of, or are in the process of entering, the European Union and NATO which leads to the harmonization of their legislation and systems in the fields of criminal justice and security. This anthology covers a range of very diverse topics from policing, criminal justice, criminology, information security, and wider security issues.
