"Professionals, too, proved exceptionally susceptible to Hitler's appeal. Lawyers and doctors were substantially over-represented within the NSDAP, as were university students (then a far narrower section of society than today). To fat middle-aged lawyers, he was the heir to Bismarck. For their sons, he was the Wagnerian hero Rienzi, the demagogue who unites the people of Rome. 'Right down to the last, deepest fibre in myself, I belong to the Führer and his wonderful movement,' wrote the Nazi lawyer Hans Frank in his diary after a concert he had attended with Hitler on February 10, 1937. 'We are in truth God's tool for the annihilation of the bad forces of the earth. We fight in God's name against Jews and their Bolshevism. God protect us!' Such thoughts helped him and many other lawyers to come to terms with the systematic illegality that characterized the regime from the very outset: the arrests without trial (26,000 people were already in 'protective custody' as early as July 1933), the summary executions (beginning with the Night of the Long Knives in June 1934, when between eighty-five and two hundred people, including the over-mighty leaders of the SA, were murdered in cold blood) and, of course, the escalating discrimination against racial and social minorities."
