I have been curious about how Norwegians who joined the SS, and alternatively other occupied nazi supporters from european countries, were treated after the war. Did they hide their past, were they treated as POWs, or maybe even flee somewhere?
Some, but not all, Norwegians who joined the SS were tried for treason (although not for any war crimes they might have committed abroad), and some were executed. The other 3 major groups which were punished after the war were Norwegian policemen who had assisted the German occupation; members of the paramilitary, collaborationist 'Rinnan gang' who answered to the SD and infiltrated the Norwegian resistance; and senior members of the Norwegian fascist Nasjonal Samling party. The postwar tribunals occasioned a lot of debate within Norwegian society, as to both the selectiveness of the prosecutions and the larger question of capital punishment (the last peacetime execution in Norway occurred in 1876, and capital punishment in peacetime was formally ended in 1905).
