Sure-but we can't be sure we have the same versions of the book, so you'll want to check the chapters as well. Near the end of chapter 25—on page 240 of my version of the book—you'll find this tragic line: "Maycomb was interested by the news of Tom's death for perhaps two days; two days was enough for the information to spread through the county."
Why this line? Because what happened to Tom was a genuine tragedy, and only a place defined by the three themes you mention could have a tragedy pass so quickly, with their attention then moving on to other things. In other words, you'd have to be racist, ignorant, etc., to stop hurting so quickly.
here is one i wrote myself for an essay
"i hope and pray that i can get Jem and Scout through this without bitterness...why reasonabl people go stark raving mad when anything about a negro comes up, is something i don't pretend to understand... i just hope that Jem and Scout come to me for thier answers instead of listening to the town" (end of ch. 9, just befor ch. 10) this shows how ignorant people can be about races. people are really hard on Atticus because he deffends a black man. This puts the reader in his shoes and helps us see him as a father/victim. this gives the reader a feel for his character and what he has to go through, as well as how the town feels about his decision to defend tom robinson.
“Why reasonable people go stark raving mad when anything involving a Negro comes up, is something I don't pretend to understand.”Chapter 9
