as a model for Nazi legislation to target Jews in Germany. Freisler considered American Jim Crow racist legislation "primitive" for failing to provide a legal definition of the term black or negro person. Nevertheless, while some more conservative Nazi lawyers objected to the lack of precision with which a person could be defined as a "Jew," he argued that American judges were able to identify black people for purposes of laws in American states that prohibited "miscegenation" between black and white people, and laws that otherwise codified racial segregation, and, therefore, German laws could similarly target Jews even if the term "Jew" could not be given a precise legal definition. In 1933, he published a pamphlet calling for the legal prohibition of "mixed-blood" sexual intercourse, which met with expressions of public unease in the dying elements of the German free press and non-Nazi political classes and, at the time, lacked public authorization from the policy of the Nazi Party, which had only just obtained dictatorial control of the state. It also led to a clash with his superior Franz Gürtner, but Freisler's ideological views reflected things to come, as was shown by the enactment of the Nuremberg Laws within two years. In October 1939, he introduced the concept of 'precocious juvenile criminal' in the "Juvenile Felons Decree". This "provided the legal basis for imposing the death penalty and penitentiary terms on juveniles for the first time in German legal history." Between 1933 and 1945, the Reich's Courts sentenced at least 72 German juveniles to death, among them 17-year-old Helmuth Hübener, found guilty of high treason for distributing anti-war leaflets in 1942. On the outbreak of World War II, Freisler issued a legal "Decree against National Parasites" (September 1939) introducing the term perpetrator type, which was used in combination with another Nazi ideological term, parasite. The adoption of racial biological terminology into law portrayed juvenile criminality as 'parasitical', implying the need for harsher sentences to remedy it. He justified the new concept with: "in times of war, breaches of loyalty and baseness cannot find any leniency and must be met with the full force of the law." Wannsee Conference On 20 January 1942, Freisler, representing the Reich Minister Franz Schlegelberger, attended the Wannsee Conference of senior governmental officials in a villa on the southwestern outskirts of Berlin to provide expert legal advice for the planning of the destruction of European Jewry.
