Old Sarum bunch could cause some problems. Atticus dismisses their concerns but the men

considered a special occasion.

the other men visit Atticus's home to warn him about the Old Sarum bunch. They fear that the Old
Sarum bunch will form a lynch mob and attempt to hang Tom Robinson before the trial. The men are
Atticus's friends and simply looking out for him. Although Atticus dismisses their concerns, he
