Read it through once

Homer Plessy was arrested for sitting in a whites-only passenger car on June 7, 1892, and one month later he stood before Judge John Howard Ferguson to plead his case. Plessy was an octaroon who could easily "pass white." Four years later, the Supreme Court condoned "Separate but Equal" laws in the famous Plessy vs. Ferguson case, which affirmed the decision of Justice Ferguson in local court. These events in 1892 unfolded as Twain wrote this story, and changed the tale that he ended up telling.
