The overall progress of society, as well as socially damaging phenomena which society confronts in an institutional manner, is increasing and complicating the police apparatus. However, in the context of dealing with activities aimed at gathering information and evidence related to criminal offenses, including offenses in the sphere of organized crime and corruption, and research trends of property acquired with those works, takes special attention to the role of the Criminal Investigation Department, or its organizational units specialized in the fight against organized crime, or other specialized bodies. The interactions of various factors within the police service and outside, which find the origin of activity in the same mission, are a potential source of disagreement, and it emphasizes the characteristics of the police profession, and the associated subculture. This paper analyzes the general characteristics of the police profession that can have repercussions on the efficiency of financial investigations and the necessary conditions that favor their success, and processes in which police officers involved in financial investigations are exposed to, in order to improve efficiency. Also, the paper identifies other circumstances, at the strategic and operational level, which can significantly affect the results achieved in the investigation process. Good cooperation among the subjects of criminal and financial investigations, starting financial investigations immediately after getting information about the crime and the assets obtained, and specialization of investigative subjects are only basic elements needed for success in financial investigations. Besides these, it is possible to identify a number of objective or subjective factors, which may affect the success of the implementation of financial investigations, which are mentioned in the paper. Special attention, especially in the context of societies with underdeveloped institutions and the questionable rule of law, deserves the will factor. Aforementioned factor emerges as a key element that can significantly affect the success of the research team, and indeed the expected results. It is therefore desirable that the general interest, presented in the normative framework, is consistent with the prevailing beliefs of research subjects, i.e. it is essential that these entities have a high degree of belief in the purpose and validity of what they do. Otherwise, the results will be absent, and the regulatory framework will appear as an empty form, without meaning and content. Sa opštim napretkom društva, kao i društveno štetnih pojava kojima se društvo suprotstavlja na institucionalan način, uvećava se i usložnjava i policijski aparat. Međutim, u kontekstu bavljenja delatnostima usmerenim na prikupljanje informacija i dokaznog materijala vezanog za krivična dela, uključujući i krivična dela iz sfere organizovanog kriminala i korupcije, kao i istraživanje tokova imovine stečene tim delima, posebnu pažnju zauzima uloga kriminalističke policije, odnosno njenih organizacionih jedinica koje su specijalizovane za borbu protiv organizovanog kriminala, odnosno drugih specijalizovanih tela (najčešće agencija ili posebnih istražnih subjekata). Interakcije različitih činilaca, u okviru policijske službe ili šire, čije delatnosti pronalaze ishodište u istoj misiji, potencijalni su izvor nesuglasica, što u prvi plan stavlja karakteristike policijske profesije, odnosno pripadajuće supkulture. U radu su analizirane opšte karakteristike pripadnika policijske profesije koje mogu imati reperkusije na uspešnost u finansijskim istragama kao i neophodne pretpostavke koje idu u prilog njihove uspešnosti, odnosno procesi kojima su izloženi policajci angažovani u finansijskim istragama, u cilju poboljšanja efikasnosti. Takođe, identifikovani su i druge okolnosti, na strategijskom i operativnom nivou, čije ostvarenje može znatno uticati na ostvarene rezultate u istraživačkom procesu.
