Litten cross examined Hitler for three hours, finding many points of contradiction and proving that Hitler had exhorted the SA to embark on a systematic campaign of violence against the Nazis' enemies. This was crucial because Hitler was meanwhile trying to pose as a conventional politician to middle class voters and maintained that the Nazi Party was "strictly legal". Though a judge halted Litten's questioning, thus saving Hitler from further damning exposure, newspapers at the time reported on the trial in detail and Hitler was investigated for perjury that summer.
