Over the last decade, the Netherlands has ceased to regard crime, disorder, and safety problems as the responsibility of just the police resulting in the emergence of a great number of multi-agency security networks and partnerships, especially on the local level. The first local security networks, introduced in 1986, were seen as potentially being the answer to a combination of factors. This paper analyzed the great diversity of local security networks by distinguishing four network models: participatory networks, mixed enforcement networks, preventive institutional networks, and reactive institutional networks. The problems that confront security networks depend to a large degree on the underlying model(s). The paper is based on a study of local security networks in the Netherlands with eight such networks studied in detail. The analysis shows that it is important to distinguish clearly between different sorts of local security networks. The problems local security networks are confronted with depend to a large degree on the underlying network models. Each model has its specific problems with some problems resulting from the tensions between the logic or demands of one or more underlying models. References
