I'm sorry you find a Wikipedia article documenting a historical event so beneath you. It must also be flippant remark day, and I didn't notice.
I found some interesting parallels. I like the idea of a few individuals rising to the defense of an unfairly accused person, working together to change minds/attitudes, transforming the political landscape, and eventually exonerating him. Your intellectual dexterity should reveal to you a modern relevance. I found the letters of Émile Zola inspiring, and I thought the affair worth sharing--in case anyone didn't know about it.
