This research and analysis of the radicalization prevention model is a growing but not sufficiently researched area, especially the community policing model and its practical implications. This paper presents a unique analysis of possible preventive measures by community policing on globally growing risk factors of radicalization such as: economic crisis, injustice in the world, political disagreements in the world and at the local level, religious and ideological indoctrination of people, promotion of hatred by political leaders, dissemination propaganda, the feeling of powerlessness of the individual, media reporting and online propaganda through social networks. The study is based on a null hypothesis, which claims that there is a statistically significant correlation between the extent to which police can prevent extremism and radicalization and the factors that influence their occurrence, and was conducted on a sample of 108 Zagreb Police College students. The results indicate that the vast majority of respondents believe that police in the local community can effectively prevent radicalization processes in Croatia by appropriate or professional action in their area. Also, respondents are more inclined to believe that police in the local community can prevent the processes of radicalization in Croatia, and the sources of extremism and radicalization are mostly seen in the propagation of such views by influential public figures. Furthermore, the results of the correlation analysis indicate that the extent to which police can prevent radicalization processes is statistically significantly positively related to one factor influencing the occurrence of radicalization. Trainees who believe that the police can do a lot to prevent the process of radicalization are more inclined to believe that media coverage through magazines and TV has a significant impact on the emergence of the process of extremization and radicalization. This type of research has significant practical implications for the prevention of radicalization, as it indicates precisely what risk factors community policing and other strategic national security programs need to pay attention to.
