This paper is part of the research project "Cooperative security policy inthe city" (KoSiPol) financed by the Federal Ministry of Education and Research (BMBF) in Germany, which has been carried out from 2010 to 2012. Within this project the different partners have – from a social sciences perspective - looked at multiagency policing concepts in selected fields of local security and tried to identify the conditions under which cooperative work is successfull. Another aim was to improve the cooperation between the main public actors in this policy field – the local police forces, the local administration, social services, local business and other societal groups.
