Saleha- The Meaning of the Title?

The book To Kill A Mockingbird has a meaning hidden in the title that relates deeply with the story. The saying is that you shouldn’t kill mockingbirds because they don’t harm anyone they only sing. So in the story the mocking bird is Boo Radley. As you know Boo Radley saved Jem from Mr. Ewell. Even though Heck the police officer knew that Boo Radley was guilty of killing Mr.Ewell he still told Atticus that Mr. Ewell fell on his knife and that Jem did not kill him. Heck the police officer didn’t tell Atticus because he knows that Boo Radley had to kill Mr. Ewell to save Jem and so if he was sent to jail it would be injustice. So the story relates to this saying because even though all these years everyone thought that Boo Radley killed his father; when he saved Jem, Heck realized that Boo Radley was nice. So if he would go to jail it would be like in a way be killing the mockingbird. So the title relates to the book with a very deep and different meaning. The meaning of the title was really confusing to understand but Mr. Heneke told us how it related to the story.
