The German Congress on Crime Prevention is an annual event that has taken place since 1995 in different German cities and targets all areas of crime prevention. Since its foundation the GCOCP has been opened to an international audience with a growing number of non-German speaking participants joining. To give the international guests their own discussion forum, the 1st Annual International Forum (AIF) within the GCOCP took place June 18 and 19 2007 in Wiesbaden (Capital of the State of Hesse). For non-German guests this event offered five AIF lectures in English language as well as other activities that were translated simultaneously. This book reflects the input and output of the 1st Annual International Forum. Firstly four lectures of the AIF are printed, followed by contributions from participants of the congress. The articles reflect worldwide views on crime prevention as well as the current status, discussion, research and projects in crime prevention from different countries. The topics range from what works in crime prevention, youth and prevention, youth violence, Neighbourhood Watch and corruption. At the end the Wiesbaden Declaration is included, a report about the key findings of the Wiesbaden congress.
