Jasenovac concentration camp
After the inmates grew familiar with life in camp, they would have to get used to living through the hardships, abuse, torture, and deaths of other prisoners.  The danger of death was greatest during "public performances for public punishment," also called selections.  Inmates would be lined up in groups, and individuals would be randomly pointed out to be killed while facing the rest. The Ustaše would make this worse by making the process take a long time.  They would walk around and ask questions; gaze at inmates; choose one person, then change their mind and choose another.
