School starts. As a third grader, Scout is no longer frightened of Boo Radley. She is confused, however, when the town, which was so set against Atticus defending Tom, reelects him to the state legislature that year.
Even though Maycomb reviled Atticus for defending Tom, it seems to recognize that he's necessary. He's the town's courage and conscience.
In school, Scout's class discusses Nazi Germany. Scout asks Jem why her teacher, Miss Gates, would say persecuting the Jews is awful when she seemed so happy after Tom Robinson got convicted. Jem shouts at Scout never to talk about the trial again.
Maycomb's blindness is once again made visible. The people criticize the Nazis murderous prejudice, but don't even recognize their own.
