TKAM Chapters 18-20

At the end of chapter 20, Scout, Jem, and Dill are sure Atticus has won the case for Tom Robinson.  The evidence is pointing in every way that Tom hadn't raped Ms Ewell.  Unfortunately, this is still a time of segregation, and I have a feeling that the jury will still find Mr Robinson guilty.  Even Atticus said that he doesn't know if he will win or not, and he appeared to be very nervous while speaking.
