Who is the central figure that Bryan Stevenson advocates for in "Just Mercy"?

Bryan Stevenson advocates primarily for Walter McMillian in "Just Mercy." McMillian was wrongfully convicted of murder and sentenced to death in Alabama, a case that Stevenson takes on to expose the systemic injustices within the criminal justice system. Throughout the book, Stevenson's advocacy reveals the profound impact of racial bias, inadequate legal representation, and the harsh realities of capital punishment, all reflected in McMillian's case. Stevenson's detailed account illustrates the importance of compassion, mercy, and the need for systemic reform, making McMillian's story a central pillar of the narrative. This focus not only emphasizes the personal tragedy of McMillian's wrongful conviction but also serves as a broader commentary on the failures of the justice system towards marginalized communities.
