The use of deadly force in the Republic of Serbia is regulated by the Law on Police and the Rulebook on Police Powers. Empirical research on the use of deadly force or on refraining from the use of deadly force has never been undertaken in Serbia. Therefore, the research presented in this paper is the first on this important topic. It focuses on the use of firearms, abstinence from the use of firearms, and training in the use of firearms. In order to assess the competence of members of the Police Directorate of the Ministry of Interior of the Republic of Serbia in the use of firearms (FA), a structured questionnaire developed by using close-ended, multiple-choice questions, and 5-point Likert scale questions (1 for strongly disagree to 5 for strongly agree) was used in the study. The research was conducted from September to October 2022. The research showed that the use of deadly force by members of the police in Serbia is rare, and that it generally does not differ largely from other European countries.
