Abstract: In the context of the modern transformation of Russian statehood, attention to the problems of improving law enforcement has naturally increased. Of particular importance are the issues of the application of modern scientific achievements. It is no coincidence that over the past decade, the study of the process of formation and development of criminal investigation has noticeably intensified.
The object of the study is the activity of the East Siberian Criminal police aimed at combating criminal crime, the subject is the implementation of this activity through the introduction of advanced scientific achievements. The purpose of the study is to determine the content, trends, patterns and contradictions of the process of formation and development of criminal investigation.

The scientific novelty of the study lies in the analysis of the features of the introduction of advanced methods of investigation into the activities of the police of Eastern Siberia.
The practice of combating criminal crime in pre-Soviet times on the territory of Eastern Siberia demonstrated the urgent need to apply the latest achievements of science and technology. Due to the lack of effective means and methods of identifying criminals, the criminal investigation system of Eastern Siberia did not fulfill its main tasks. Already in the second half of the XIX century, the steady decline in the personal and property security of the Siberian population required the local administration to take the most drastic measures. One of the most promising areas of combating criminal crime was the use of advanced methods of investigation. However, due to financial difficulties, the use of promising methods in operational activities for many years remained only the lot of single enthusiasts. The remoteness from the metropolis, the personnel crisis and insufficient funding had a decisive impact on the very possibility of using advanced scientific and technical achievements in detective work.

Abstract: The authors consider the peculiarities of internal affairs officers training for emergency mitigation in air transport. The problem of underpreparation of police officers for emergency and search and rescue operations in specific circumstances of emergency mitigation in air transport hasn’t been solved during a long time by now. The adoption of optimal forms and promising educational methods in the process of professional training of internal affairs officers is believed to be one of the ways to solve the problem. The article considers the possibilities of using the methodology of situational approach for the organization of training in the form of staff exercise, tactical and special training and tactical and special exercise. The authors suppose that the introduction of such educational forms into the educational practice will allow forming the necessary professional competencies. The use of staff exercise, tactical and special training and tactical and special exercise in the educational process not only helps develop the required skills, but also trains psychological resistance which helps perform operational tasks of this type fully and within the allotted time.
