Watch this video segment—adapted from AMERICAN EXPERIENCE: "The Murder of Emmett Till”—to learn the story of a 14-year-old black boy who was brutally murdered on a visit to Mississippi from Chicago in 1955. After Emmett whistled at a white woman, he was beaten and murdered by two white men; they were later found innocent by an all-white jury. Emmett’s tragic death and the subsequent publicity about the trial helped spark the Civil Rights Movement in the 1950s.
