How is systemic racism shown in the novel?

Not only does To Kill A Mockingbird deal with themes of prejudice, it also delves into institutional racism. Although many people are victims of prejudice for various reasons, the novel shows that state violence against black people is an institutional and systemic hatred. Through the portrayal of the criminal justice system and the prison system, the novel shows how injustice is not only perpetuated by individual people, but by a whole system that needs to change. Because despite the honorable work of people like Atticus Finch, and despite the overwhelming amount of evidence that Tom Robinson is innocent, Tom’s life is destroyed anyways.
