In the novel To Kill a Mockingbird, how do Scout and Jem support Atticus in the pursuit ofjustice?
There are several ways in which this occurs.
First, in chapters 14-15, just before the trial, Scout and Jem sneak out and follow Atticus to the jail. At this point, they find a mob of men confronting Atticus and they unknowingly ensure that they do nothing to Tom Robinson or Atticus. They diffuse the men's rage because Scout asks Mr. Walter Cunningham questions.
Throughout the book, Atticus claims that he has to do this (defend Tom Robinson) because he is accountable to do the right thing because his children are watching. He can't tell them to do the right thing and then do another.
After the trial (chaps 21-23) Atticus experiences Jem's clear understanding of the evidence and how the trial should have turned out. This must give Atticus faith in a new generation that there is the opportunity for kids to turn out in a way that they might do right. He talks about how the courts should be the great equalizers, but that in men's hearts, that's not always the case. Atticus feels supported because he knows Jem wants to see justice achieved.
