Why do you think the Germans chose to hang the black market goods dealers and leave them in the street for a full week? What do you think they were trying to convey to the other jews?

The men were hung as an example; they were left handing as a threat and reminder of what would happen to those who were caught dealing selling or trading goods illegally.

Note: you only need to ask your questions once. They will always be handled in a timely fashion.
