Yes it is.

Something about them getting an all White Jury.

The jury in "To Kill a Mockingbird" is made up of white men from Maycomb County. They are all male and all white, reflecting the racial and gender biases of the time period in which the novel is set.

Atticus fears that the jury will make the assumption that Tom Robinson is guilty primarily because he is a black man accused of assaulting a white woman, despite the lack of credible evidence supporting the accusation. He worries that racial prejudice will cloud the jury's judgment and prevent them from delivering a fair verdict.

he doesnt because the thinks that it is not fair that it is all white people and no blacks
