Yes, very little interest.
Germany is currently trying Heinrich Boere, an SS man who killed a number of Dutch civilians, and was tried in absentia, his choice not to show up, and sentenced to death in the late 1940s. Dutch pop, but a German mom, thus a German citizen, and Germany doesn't deport their citizens. Even German war criminals in the post war period. And, well he killed Dutch folk in their country, so no crime in Germany. He lived a free life in Germany, till now.
See, if we can find them, we can tie them up and pour gasoline on them — for the sake of science.
