What does Stevenson identify as one of the greatest barriers to justice?

Stevenson emphasizes systemic racism as one of the greatest barriers to justice throughout "Just Mercy." He illustrates how racial discrimination is deeply entrenched in the American legal system, impacting not only the treatment of individuals in courtrooms but also the broader societal attitudes towards people of color.

Stevenson discusses various historical and contemporary examples that highlight how race influences the likelihood of harsher sentences, wrongful convictions, and the overall treatment of defendants. This systemic issue perpetuates inequality and reinforces cycles of poverty, disproportionately affecting marginalized communities. By focusing on systemic racism, Stevenson calls for a re-examination and overhaul of the justice system to address these fundamental injustices and promote true fairness for all individuals, regardless of race.

While poverty, lack of education, and public apathy are significant issues that also contribute to challenges within the justice system, Stevenson's specific emphasis on systemic racism underscores its pervasive impact and the urgency of addressing it to achieve meaningful reform.
