What is the main focus of "Just Mercy"?

The main focus of "Just Mercy" is to examine racial injustice and the failures of the criminal justice system. The book highlights the systemic issues that disproportionately affect African Americans and other marginalized groups, particularly in the context of wrongful convictions and harsh sentencing. Bryan Stevenson uses his experiences as a lawyer to illustrate how racial bias impacts the legal process, often leading to severe injustices for individuals who are poor or who belong to minority communities. The narratives presented throughout the book, particularly that of Walter McMillian, serve to expose the deep-seated inequities within the system and advocate for reform and compassion in the administration of justice.
