Riefenstahl  continued to maintain she was "fascinated" by the National Socialists  but politically naïve and ignorant about any war crimes. From 1945  through 1948 she was held in sundry American and French-run detention  camps and prisons along with house arrest but although Riefenstahl was  tried four times by various post-war authorities, she was never  convicted through "denazification" trials either for her alleged role as  a propagandist or for the use of concentration camp inmates in her  films. However, she was found to be a "fellow traveller" who was  sympathetic to the Nazis.
 Riefenstahl  later said that her biggest regret was meeting Hitler: "It was the  biggest catastrophe of my life. Until the day I die people will keep  saying, 'Leni is a Nazi', and I'll keep saying, 'But what did she do?'"  She won more than 50 libel cases against people accusing her of  knowledge having to do with Nazi crimes.
