Final answer:
The original jury in the Scottsboro Boys trial was entirely white, and they swiftly convicted the nine Black boys despite exculpatory evidence. One Black juror was eventually included in a third trial. The cases exemplified the racial injustice of the legal system during that era.
Step-by-step explanation:
The racial makeup of the original jury at the trial of the four officers, who are better known as the Scottsboro Boys, consisted entirely of white individuals. This all-White jury quickly convicted the nine Black boys based on false allegations. Despite evidence that contradicted the women's accusations and one of the accusers recanting her testimony, the trials revealed the racial biases and potential for injustice within a jury system that excluded Black jurors. It wasn't until a third trial that a single Black juror was included, marking the first time a Black juror had sat on a grand jury in Alabama since Reconstruction. Even with this inclusion, the overwhelmingly white jury once again voted for a guilty verdict and the death sentence due to the laws at the time allowing an indictment with a two-thirds majority.
