In chapter 20, Dill and Scout interact with Dolphus Raymond outside of the courthouse, and they discover that he feigns alcoholism in order to maintain a low profile, avoid conflict, and continue to carry on what the racist community of Maycomb considers a taboo lifestyle by associating with black people. Dolphus also explains to the children that as they grow older, they will no longer cry at the racial injustice and discrimination they witness on an everyday basis. He then tells the children,
"You haven’t even seen this town, but all you gotta do is step back inside the courthouse" (Lee, 205).
Essentially, Dill and Scout gain significant insight into their racist community during their interaction with Dolphus Raymond, and Scout learns that her father is a not a "run-of-the-mill" man. They also learn that as they grow older, they will become less affected by the racial discrimination they see on an everyday basis because it is so prevalent. At the end of chapter 21, Judge Taylor reads the verdict, and Tom Robinson becomes a victim of racial injustice by being wrongly convicted of assaulting and raping Mayella Ewell.
