TKAMB 15-16

In Chapter 15 when Atticus is confronted by all those men at the County Prison, you get a feeling that it wont end well.  Just from dialogue, you could tell that if Atticus was not there to stop them, they would have walked in and killed or severely hurt Tom Robinson because hes a black man living the time of white prodominentcy. Also later in the Chapter when it first begins, we learn that there is a good chance Mr Robinson will loose seeing the Jury is all farm folk and related to the Cunninghams.
