A mob that wants to murder Robinson gathers around the entrance to jail, where Atticus is sitting prepared to defend Robinson from the mob
"You know what we want...Get aside from the door, Mr. Finch," (172)
"He in there, Mr. Finch?" (171)
"He is... and he's asleep. Don't wake him up," (171)
Atticus is prepared to face the mob and protect Robinson, but Scout, not completely understanding, jumps in and begins talking to one of the members about his son. The man is ashamed and tells the rest of the mob to leave.
"I'll tell him you said hey... Let's get going boys," (175)
"Don't you remember me Mr. Cunningham? I'm Jean Louise Finch. You brought us some hickory nuts one time, remember?... I go to school with Walter... He's your boy, ain't he?... Tell him hey for me, won't you?" (174)
"This case is as simple as black and white. The state has not produced one iota of medical evidence to the effect that the crime...ever took place... It has relied instead upon the testimony of two witnesses whose evidence has not only been called into serious question by cross-examination, but has been flatly contradicted by the defendant," (231)
Atticus provides clear and solid evidence that Robinson is an innocent man, explaining that the Ewell family was embarrassed by their daughter's decision to be with a black man, and using the marks on their daughters face as proof, along with many other points proving his case.
"I shut my eyes. Judge Taylor was polling the jury: 'Guilty...guilty...guilty...guilty,'" (240)
"It was Miss Stephanie's pleasure to tell us this: this morning Bob Ewell stopped Atticus on the post office corner, spat in his face, and told him he'd get him if it took the rest of his life," (247)
"Tom's dead...They shot him...He was running...They got him just as he went over the fence. They said if he'd had two good arms he'd have made it, he was moving that fast. Seventeen bullet holes in him," (268)
The jury gives Robinson a verdict of guilty, despite the overwhelming evidence. The conclusion was reached based on the color of his skin and it was known that a white man in this situation would not have reached this outcome.
Ewell wants revenge on the Finch's and anyone involved in the trial for embarrassing him and his family, despite the verdict.
Robinson tries to escape prison, knowing that he would be executed anyways, but is shot seventeen times and is killed. Jem begins his questioning of the justice system which eventually ends up in him believing that the whole justice system is corrupt.
