The jury sat to the left, under long windows. Sunburned, lanky, they seemed to be all farmers, but this was natural: townsfolk rarely sat on juries, they were either struck or excused.

– Harper Lee

To Kill a Mockingbird, Chapter 16. Scout describes the jury. It is made up of the country folk of Maycomb, farmers, since the townspeople were usually able to get out of jury duty. The all male, all white jury, with no women or minorities on it, is not representative of Maycomb County. Straight away a black accused is at a disadvantage.
