Among the initial tactics of Nazi authorities was to surreptitiously encourage and involve the local population in attacks on Jews. These tactics are well disclosed in the Schutzstaffel General Brigadeführer and Security Police Chief of the Occupied Eastern Territories Franz Walter Stahlecker October 15, 1941 report to the Reich Minister Heinrich Himmler. In this report Stahlecker states that the extermination of Jews in the Wehrmacht-occupied territories should be performed in a way that the Nazis would remain "clean" and that there would be no sign of Nazis actual inspiration, organization or conducting, and it should look like that the local population and its institutions in their own initiative performed the execution of the Jewish population. In this regard, the LAF and its paramilitaries initially proved handy. But later Stahlecker complained that it was "not a simple matter" to organize Lithuanians into actions against Jews.
