Despite all measures taken both at national and international levels, violence at sporting events continues to be a particularly complex security problem, in the solution of which the police have an important and delicate role, along with other subjects. In formal and legal terms, more or less clearly, the role of police in the Republic of Serbia is defined primarily by the Law on Police and the Law on Prevention of Violence and Misconduct at Sport Events. Some, usually legal, conceptual, and tactical aspects of the role of the police are increasingly being addressed by numerous vocational and scientific papers. However, they only sporadically investigate models of the organizational structure of the police, which undoubtedly present an important factor in successfully securing certain sport events, and thus in preventing and combating violence on the occasions of such events. Considering that police protection of every sport event, as a public meeting, has the basic characteristics of a specific project, the application of project management of the police seems to be logical in carrying out security tasks. On the other hand, given the fact that such police activity involves some temporary integration, in particular of some special and various police units, it seems logical to apply the matrix (functional and project) model of the organizational structure. This paper analyzes the impact of these and other specific characteristics of sport events on the selection of and creating an optimal model of the police organizational structure, which ensures effectiveness in achieving the goals of preventing and combating violence at sport events and organizational effectiveness in the use of police resources in achieving these goals.
