The notion that the police need to work in interorganizational partnerships has been well-established for decades, although the task has proved difficult. Based on interviews with representatives from strategically selected CSOs, this study examines encouraging and hindering factors for collaboration with the police. It also shows that the statements of the three CSOs echo previous research where the police is involved. The study concludes that firstly, the police must recognize the CSOs as trustworthy and consider their activities to be of police interest. Secondly, the CSOs must manage to penetrate the police organization's physical and cultural boundaries in order to offer their services. Thirdly, a division of labour must be established where the benefits of collaboration are evident for both parties. Fourthly, collaboration must be organizationally institutionalized. It is worth noting that not all CSOs strive for closer collaboration; some prefer to keep a distance.
