The more prominent men of Maycomb assemble in the Finch front yard in order to speak privately to Atticus about getting a change of venue for the trial of Tom Robinson in order to prevent a lynching or other problems.
This meeting of the businessmen and sheriff is a "let this cup pass" moment much like the one between Atticus and his brother Jack in Chapter 9 in which Jack asks Atticus "how bad" the forthcoming trial of Tom will be. As he speaks privately to his brother, Jack asks Atticus if he can avoid being involved--"Let this cup pass from you, eh?"
The Maycomb men who have much invested in their town have their worries voiced by Mr. Link Deas who observes that the townspeople present no problem; however "It's that Old Sarum bunch I'm worried about...." Clearly, this is a "[L]et this cup pass" moment for the assembled men. But, Atticus is stalwart in his determination to provide Tom his rights under the Constitution:
"Link, that boy might go to the chair, but he's not going till the truth's told....And you know what the truth is."
Truly, this meeting with the townsmen is another illustration of the integrity of Atticus Finch, who is willing to risk his own personal safety in order to provide justice under the law for the innocent Tom Robinson.
