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 dis-cussion 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 activities within the GCOCP that are translated simultaneously. This book reflects the out-comes of the 11th AIF (19th and 20th June 2017 in Hanover). The articles show worldwide views on crime prevention and criminal policy as well as the current status, discussion, re-search and projects in crime prevention from different countries.
