International police and other cooperation is a necessity of the modern world and imperative for the survival of human civilization. The goal of cooperation is that states and the international community unite in opposing crime as the greatest peacetime evil in the world. This is particularly in relation to organized crime, terrorism, and corruption and other most serious forms of crime in contemporary society. Cooperation takes place at the bilateral, regional and multilateral levels. Bilateral cooperation mainly has a trans-border character of neighboring countries, while the regional cooperation between states within certain areas such as the SEE region (Western Balkan) or Europe (e.g. Europol). Multilateral cooperation is mainly on a broader level, e.g. in the field of combating terrorism or through universal organizations (e.g. Interpol). International police cooperation in Europe has a long tradition. One part takes place today in this area through the OSCE, with the caveat that this is a global organization that deals with security issues. The Council of Europe is the next organization through which co-operation began in the past and is partly carried out to this day, given that it brings all European countries together (except Belarus). Cooperation is more intensive still throughout the European Union, its forerunners, the current forms of the organization and present mechanisms (EAW- European surrender and arrest warrant).53 The cooperation in the EU, that takes place through Europol as a specialized agency of the Union is especially current, but with minimal operational competencies. In the SEE region, a significant cooperation between countries of the former Yugoslavia and countries in its neighborhood has been achieved. This cooperation is not only based on bilateral and multilateral acts, but primarily regional documents of which the most important are the International Convention on Police Cooperation in SEE and SELEC Convention. According to these and other acts, all the countries in the region have taken part in regional cooperation, since the fight against crime is the common interest of all. This applies in particular to organized crime, terrorism, corruption and other most serious forms of crime. Extremely important shapes, forms and mechanisms of international police cooperation are: exchange of information, joint investigation teams, joint operational actions, liaison officers, contact points, regional centers for police and customs cooperation, joint police stations and others. To recap, international police cooperation in the world today is an expression of anti-criminal solidarity between states and its prospects are clear, because the danger of crime is global and requires a harmonized response at the international level.
