Participation processes offer many advantages for the police. The benefit of communicative processes of citizen participation in police work not only has an external effect (external impact) on the population, but also an internal effect within the police organization itself (internal impact). A cooperative and trustful collaboration with the citizenry offers the police the opportunity for context-specific conflict resolution in advance of tension-filled protest actions. This trust-based collaboration is expanded in innovative participatory projects and networks at the municipal level. A gain through participation processes for the police has an internal effect, through valuable and free expertise from the citizens’ perspectives and the associated more holistic reflection on operational and professional roles and questioning of the police’s interpretive and discursive power. In this way, the relationship between the police and the population can gain mutual trust and strengthen democratic negotiation processes around conflict-prone topics and operations. An excursion describes citizen participation procedures also as a prerequisite for organizational learning in the police.
