This project is about the Swedish intelligence service, its operational culture and internal norm system during the Second World War and the post-war period. The focus is on Thede Palm and Jan Rydström, two men with leading positions in the intelligence sphere, and their until recently classified documents. The aim is essentially political and philosophical, and is based on the paradoxical fact that liberal democracy accepts its opponents. Thus, the system has its allure but also its potential downfall. In order to protect themselves from destruction, the representatives of the democratic system are therefore sometimes forced to resort to non-democratic methods. In doing so, they run the risk of becoming like their opponent. What can be allowed in the name of prevention is therefore subject to individual opinions and attitudes and is in a gray area. Intelligence organizations have a constitutional protection goal, but achieving this goal sometimes requires unconstitutional, or at least dubious, means. Thus, the intelligence service has to deal with the grey area mentioned above, and different actors' - Palm's, Rydström's but also others' - perceptions of where the boundaries in this grey area lie reflect the culture that prevails within the organization. Which norm system should prevail? What can be allowed in the name of constitutional protection, and what cannot be allowed? Where does the line go? It is questions like these that the actions of Palm and Rydström can shed light on.
