The aim of the study is a comparative analysis of the socio-cultural aspect of criminal law enforcement in the Russian mentality. The methodological basis was such scientific methods as dialectical, comparative, logical, historical, prognostic, and systems analysis. This allowed, to achieve this goal, to perform a comparative analysis of the works of Russian and foreign legal experts on the examined problem. The result of the study was the conclusion that the effectiveness of law enforcement is due not only to national mentality, but also to the socio-cultural environment both on the part of the law enforcement officer and citizens as participants and/or eyewitnesses of specific legal relations. The authors also emphasize that culture, as well as socio-cultural environment forms stereotypes of legal behavior, depending on the constitutional and legislative consolidation of socio-political and socio-economic trends in the development of society. The novelty of the work lies in the formulation of the problem and its substantiation. This is due to the fact that the authors emphasize that an essential element is the degree of acceptability of value stereotypes in a particular state that allow and/or prohibit certain actions in connection with the possibility of undermining the foundations of national security and public morality.
