Abstract: The object of research is neural networks, the VKontakte platform, the Telegram messenger, the Python programming language and its libraries, and a block diagram of a computer system model. The subject of the study is a computer technology for detecting extremist content in text form and specific groups containing it on the VKontakte social network. The authors consider in detail the structural scheme of the computer system model, the functional modules included in it, and illustrate their interaction. The paper uses a pre-trained model designed for processing the Russian language, and provides conditions for ensuring high accuracy of recognition of illegal content without signs of retraining. The paper presents the results of checking the test data confirming the operability of the computer system. The proposed prototype of the computer system ensures its integration with the Telegram messenger, which increases usability and facilitates the process of generating queries and reports. The novelty of the research lies in the creation of a prototype of a computer system for searching and detecting extremist messages on the VKontakte social network using the Python programming language and the VKontakte API programming interface (VK API). The basis of the prototype computer system is a neural network that works with the Тгаnsformers and Тоrch. A special feature of the computer system is the ability to analyze messages on a social network and subject them to binary classification for the content or non-content of illegal information in messages. The main conclusions of the study show the efficiency of the system, the simplicity and convenience of its use, the possibility of detecting illegal text content. A distinctive feature of the prototype is the ability to detect illegal content presented using slang expressions.

Abstract: The subject of the study is the classification of special equipment of the internal affairs bodies, the grounds for its classification, the requirements for the names of groups of equipment. The object of the study is the normative legal acts of the Ministry of Internal Affairs of Russia, containing information about the concept of "special equipment of internal affairs bodies", about its division into groups reflecting the system of scientific and technical information adopted by the Ministry of Internal Affairs, as well as scientific works devoted to classification as a method of scientific research, educational literature in this subject area. Using scientific methods of cognition, such as induction, deduction, analysis, synthesis, classification, the authors discuss the concepts of "special", "technique", "special technique of internal affairs bodies", contradictions in regulatory legal acts reflecting the classification of the above-mentioned technique.
The novelty of the study lies in clarifying the concept of "special equipment of internal affairs bodies", identifying criteria for attributing technical means to this group. The choice of a universal basis for classification, such as the purpose of technology, is justified. The division of special equipment of internal affairs bodies into groups has been carried out and their names corresponding to the terminology of state standards and departmental regulatory legal acts have been proposed.
The main result of the work is the development of a draft structure of the List of samples (complexes, systems) of special equipment accepted for the supply of internal affairs bodies of the Russian Federation. It is proposed to supplement its content with the sections "Special equipment", "Conventional equipment", "Equipment" and adjust the name.

Abstract: The article contains the author’s technique of formation of radio communication skills during the process of local police officers training within the practical lessons in the discipline “Special technique of internal affairs bodies”. This technique helps to form necessary competences in the sphere of service radio communication with minimum participation of a teacher in the process of radio communication. The research contains samples of educational materials (procedure charts, radio communication control charts for the operator of the main communication station, a radio communication control chart for the teacher), necessary for a lesson. The author considers the knowledge assessment criteria for the section “Means of communication of internal affairs bodies”, related to radio communication.
The topicality of the research is determined by the necessity to form stable skills of using service radio communication and radio exchange during the local police officers service. The author emphasizes that pedagogical literature doesn’t cover this issue. 
The scientific novelty of the research consists in the development of the author’s technique of formation of practical skills of radio communication within the educational process preparing the future local police officers. The technique contains the action plan for a teacher, the samples of educational materials, and knowledge assessment criteria, and helps to effectively form radio communication competences of students. The main approaches of this research can be used for other specializations.
