Klaus Croissant was a German lawyer known for his defense of Red Army Faction members, including Andreas Baader and Ulrike Meinhof, during the 1970s. His legal career was marked by controversy, leading to his imprisonment for supporting a terrorist organization. After his release, Croissant became involved with the East German Stasi as an informant. He later engaged in political activities with Berlin's Alternative Liste and, after 1990, the PDS. Croissant passed away in 2002. ([en.wikipedia.org](https://en.wikipedia.org/wiki/Klaus_Croissant?utm_source=openai))
