Browning is more interested in the experiences of the people with direct involvement in the violence (such as shooters, guards, ghetto clearing units, and so on) because they had to leap far more mental hurdles to cope with their actions than a “desk murderer” who simply signs a piece of paper or writes up a report. The general belief behind this is that doing the actual shooting has a different psychological effect than writing up and delivering orders from a distance. Reserve Police Battalion 101 provides an ideal case study because, as Browning has explained, there are numerous firsthand accounts of their actions given by the perpetrators themselves.
