Answer:
In the book "Just Mercy" by Bryan Stevenson, the protagonist encounters several obstacles preventing him from helping Walter McMillian. Some of these obstacles include:
Racism and systemic oppression: Walter was wrongfully convicted in a trial that was tainted by racism and rampant corruption. The criminal justice system was stacked against him because of his race, and he was not given a fair trial.
Opposition from local officials: Officials in the legal system, as well as others in the community, did not want Walter's conviction overturned. They felt that it would be an insult to the police and prosecutors who had worked on the case, and that it would make them and the system they believed in appear weak.
Limited resources: Bryan's organization, the Equal Justice Initiative, faced limited resources and did not have the same connections and resources as the state or the legal system. This made it difficult for him to gather the evidence he needed to exonerate Walter.
Bryan kept encountering these problems because they are deeply ingrained in the social, cultural, and political structures of our society. Institutional racism and corruption make it difficult to achieve justice, and Bryan had to work against a system that was designed to protect those in power rather than provide justice for the vulnerable. Despite these challenges, Bryan persisted in his mission to achieve justice for Walter and other people of color who were wrongfully convicted.
