The expansion of organized crime and terrorism in conditions of social and economic crisis, armed conflicts and political instability of the last decade of the XX century, have made it difficult for the Republic of Serbia to fully develop its institutional capacities, standards and procedures for more effective prevention and suppression of these forms of crime, as well as for the protection, help and support to the victims. At the same time, the existing standards and procedures are not fully harmonized with the standards and procedures of various forms of international integrations, towards which the Republic of Serbia inclines. This, besides the inefficiency of the state, obstructs the successful international cooperation in the field of crime investigation, as well as other forms of cooperation in the security field. Presently, the problem is being mitigated through the cooperation with the international community, certain international organizations and countries. From the aspect of Serbian candidacy for the membership in international organizations, above all European Union, this is inadmissible, due to the fact that international integrations imply both the independency and efficiency of the states in control of challenges, risks, and threats to the security. As one way for improvement of security practice, the Academy of Criminalistics and Police Studies in Belgrade started the realization of the Scientific Research Project entitled 'The Development of Institutional Capacities, Standards and Procedures for Combating Organized Crime and Terrorism in the International Integration Conditions'. Generally, this research is expected to provide the new theoretical knowledge on etiological, phenomenological, victimological and consequential dimension of organized crime and terrorism in the Republic of Serbia, as well as proposals, guidelines and solutions for strengthening the institutional capacities and harmonizing the standards and procedures of the security and criminalistic practice of the national security system with the demands of international public and criminal law.
