I was talking with an Austrian sociologist the other day, and he told me something interesting: that the German detective series Tatort is guided by a set of principles that determine how it portrays violent crime in Germany. The idea is to present millions of TV viewers with an image of the root causes of crime that will dampen their desire for retribution and harsher penalties. Therefore, criminals on Tatort almost always commit their evil deeds because of outside forces, such as mountains of debt, cultural expectations, social deprivation, mental illness, post-traumatic stress disorder, etc. Thus, one of the goals of Tatort is to counteract the idea that criminals are intentional evildoers. This colleague said that this is a well-known fact about Tatort, but wasn't able to point me to a source right off-hand.
Given my previous posts on West German and East German detective series (plus academic interests), I'd really be interested in a written source that would bolster the argument that Tatort scripts have a "popular education" purpose. Thanks in advance for any help.
