Jem and Atticus converse about some of the obvious problems with the legal system. What are Jem's major points, and how does Atticus address them?

In Chapter 23, Jem and Atticus talk about what keeps people off of juries. Women can't serve on juries in Alabama (which Scout takes exception to), and many people don't want to get involved in court cases because their livelihood depends in some way upon maintaining good favor with both parties involved in a case. Jem thinks that the jury decided quickly, but Atticus reminds him that it took a few hours, which is much longer than usual. Typically, a case like Tom's would be settled in a matter of minutes. Atticus sees this as a sign of the beginnings of change for the better. Also, Atticus reveals that he learned that the one jury member who kept everyone out so long was a Cunningham who defended Tom's innocence. Atticus thinks that all Cunninghams will stand solidly behind anyone who wins their respect, without fail - and the incident at the jailhouse won the Finch family great respect.
