The objective of the article is to conduct a study of the role of criminal analysis in modern models of police activity. To achieve this objective, several methods were used, namely: analysis of official documentation, scientific literature, logical analysis, concrete-historical, dialectic, or empirical methods. The article presents the most common classifications of police models today, as well as the interpretation of criminal analysis in them.
