This document presents an overview of a presentation about the (non-)participation of Belgian policemen in arresting Jews in Belgium during World War II. It discusses two requests from German authorities in 1942 for Belgian police to assist in arresting Jews in Brussels, both of which were refused. It also examines raids in Antwerp in which police either did not directly participate or their participation failed. The conclusion discusses the decentralized nature of anti-Jewish policy and questions whether there was a Western European specificity to the occupation compared to Eastern Europe.
