What does the reader assume the men from old sarum come to maycomb to do?

The reader assumes that the men from Old Sarum come to Maycomb to lynch Tom Robinson, the African American man accused of assaulting a white woman. Lynch mobs were unfortunately common during this time period in the South, and the men's aggressive and intimidating behavior suggests their intentions are violent. Their presence creates a sense of tension and danger in the community, as they are seeking to take matters into their own hands outside of the legal system.
