To Kill a Mockingbird- Why did Harper Lee make it seem like an airtight case in Atticus' favor just prior to the jury's decision?

Answer 1

Harper Lee made it seem like an airtight case in Atticus' favor just prior to the jury's decision to show the racism that was around during that time. Tom and Atticus would have won if Tom was a white man.

Answer 2

Harper Lee crafted the airtight case to highlight the injustice and racism prevalent in society by demonstrating that even with strong evidence in favor of Atticus, the all-white jury would still convict Tom Robinson due to prejudice and discrimination. This buildup of hope and optimism serves to emphasize the tragic reality of the verdict that follows.
