It’s ironic that they removed To Kill A Mockingbird because of it’s focus on civil rights in 1960’s South. IIRC, the last scene of the book is during a black man’s trial for murder, and he is being falsely accused. Scout’s father is able to prove his innocence and teach a lesson to the judge. And about causing harm to innocent people and creatures. There’s another scene in the book that regards the significance of the title but it’s just as noteworthy.
This is invaluable to high schools, personally.
