The German Congress on Crime Prevention (GCOCP) is an annual event that takes place since 1995 in different German cities and targets all areas of crime prevention. Since its foundation the GCOCP has been open to an international audience with a growing number of non-German speaking participants joining. To give the international guests their own discus-sion forum, the Annual International Forum (AIF) within the GCOCP was established in 2007. For international guests this event offers lectures in English language as well as other activi-ties within the GCOCP that are translated simultaneously. This book reflects the outcomes of the 9th AIF (8th and 9th June 2015 in Frankfurt am Main). The articles show worldwide views on crime prevention and criminal policy as well as the current status, discussion, research and projects in crime prevention from different countries.
