This chapter investigates the extent to which regional security cooperation has developed, focusing more on the everyday practice of security professions – specifically the Croatian police – and their potential role in the development of the security community in the region. By examining empirical findings from semi-structured interviews carried during 2012–2013, this research attempts to analyse the potential role of the Croatian police as a profession in the process of creating a security community in the Western Balkans. The chapter investigates how the practice of Croatian police officers has contributed to a move away from an unfavourable conflict environment and towards the creation of a community characterized by mutual confidence and 'dependable expectations of peaceful change'. Croatia's self-perception as being somewhat distinctive and the lack of a regional feeling of 'we-ness', mainly based on evident differences in development, do not necessarily imply that regional cooperation is less relevant and important for Croatia than for the region's other states.
