The police are a key actor in the crime prevention chain. The quality of relations between police officers and citizens is key in providing efficient and sound policing, which in turn contributes to the population's feeling of security. However, relations are reportedly conflictive in some European countries and cities.What is the local impact of such poor relations? What means can local authorities use to improve them? What are the existing practices? These questions will be debated during the conference among local elected representatives, national policymakers, police officers, researchers and voluntary sector representatives.Organised by the European Forum for Urban Security (Efus) jointly with the city of Brussels and the Brussels Capital-Ixelles Police Zone, this conference is part of the European project IMPPULSE (IMproving Police-Population Understanding for Local SEcurity), which was cofunded by the European Commission.
