Introduction and What does the author mean by it's a sin to kill a mockingbird?

    Over and over again I heard about how good this book is. Now I am finally reading. I am so excited.

    It's a sin to kill a mockingbird. In that statement, the author means it a sin to kill a black person. In the book a black man is falsely accused of rape. A mockingbird is a symbol of the black man. And in the bible it says thou shall not kill. Showing that the author or the lawyer was on the black man's side and they were not racist.
