I am writing a paper about mortality during the last years of Weimar Republic, namely 1928-1933. Presenting the data in Berlin, scholars wondered about the reason why the figures about people dead by murder and manslaughter (Mord und Totschlag in German) were that high. During the period 1927-1937, homicide rate has its peak at 1.9 every 100,000 people in 1932, which reported to Germany entire population of that year is around 1249 murders in a year.
I made a Google search about crime in Weimar Republic and I actually found out that high level of crimes were mostly perceived rather than actual. Indeed, there has been three serial killers during that period and a bunch of political murders but nobody consider the numbers particularly astonishing.

EDIT: I found this graph from Pinker (2011), which actually shows that Germany, even murder rate is low in absolute has the second highest value after Italy in 1920s-1930s
Still wandering why anyway.
Is anybody aware of the reason why murder rates were that high in Germany in that period? Or does anybody know sources, which may give an explanation?
