We don't see the "committee" of Jefferson Baptists who protest against allowing a woman like Ruby to stay in the town's hotel. The proprietor of the hotel refers to "these church ladies," but it's not clear whether they were the committee - or the group that sent the committee. In either case, the proprietor tells Horace that "once [them ladies] get set on a thing," a man "might just as well give up and do like they say" (180).
The musicians that Temple and her father listen to in the Luxembourg Gardens are dressed "in the horizon blue of the army" - suggesting they may be a military band, but that is not stated - and play Massenet, Scriabin and Berlioz (316).
When Temple and her father sit down "in the Luxembourg Gardens" in Paris, this is the "old woman" who comes to them "with decrepit promptitude" to collect the money - four sous - for the seats (316).
The novel's final scene "in the Luxembourg Gardens" in Paris includes a brief reference to "an old man in a shabby brown overcoat" sailing a toy boat beside the children (316).
In the hours before Popeye's execution, this minister prays for him several times, and repeatedly tries without success to get Popeye to pray for himself.
Before finding Popeye guilty the faceless jury in Alabama that hears the case against him deliberates for "eight minutes" (312) - the same amount of time it took the jury in Jefferson to decide Lee was guilty too, similarly for a crime he did not commit.
