Actually 9 of the jurors who voted were black. One was a hispinic male, the remaining two were white women. The two white women voted guilty for the first vote........but were pressured by the black majority into changing their votes to "not gulity".
"... the final jury for the trial had 10 women and 2 men, of which there were 8 blacks, 2 Hispanics, 1 half-Native American half-white, and 1 white female."
