Tom Robinson and Boo Radley are only known by what people say about them. As a result, they cannot create their own song like a mockingbird does, but their song is based on beliefs about them. For they cannot be treated like others in society. Tom Robinson was proven innocent due to the racism involved in the case. Atticus, Jem, and Scout believed in Tom's innocence because they believed everyone should be treated equally. The film represents how the justice system worked in the 1900s and the inability to provide a fair path for people of color
