Abstract: The research object is the law-enforcement activities of the bodies of the European Union. The research subject is the normative framework and the related organization and management mechanisms of crimes prevention, developed in the law-enforcement bodies of the EU, and the cooperation ties of these bodies. The purpose of the study is to establish the significant patterns of the contemporary police activities in the European Union, which have an impact or can possibly have an impact on cooperation with the Russian Federation and on Russia’s national security protection. The author applies general scientific methods of cognition and special methods of jurisprudence, ensuring the objectivity, historicism and comparativism of the study of the activities of the European police aimed at the prevention of terrorist acts and grave crimes. These methods include the principles of: the research subject development, its logical consistence, historical specificity and dialectical coherence between the logical and the historical methods of cognition; general scientific methods: system, genetic, activity; the methods of analysis and synthesis, cultural and historical analysis, the methods of comparative study, juridical interpretation and other research means of the modern social sciences. The European experience of legal and organizational regulation of activities of law-enforcement bodies in the sphere of terrorist crimes prevention hasn’t been studied thoroughly enough in Russia so far; most scientific works in this sphere focus on the political aspects of internal and foreign policy of the EU in the sphere of a “common European security space” creation. The study is based on two existing European sources of law. Special attention is given to the comparison of organizational mechanisms of registering and using the registers of terrorist organizations and terror suspects. The author substantiates the conclusion that the European law-enforcement experience of prevention of terrorism and grave crimes is highly integrated with the U.S. experience in the legal and organization spheres.
