Describe two incidents where a mob is formed in To Kill A Mockingbird, including Scout's effect on the mob. I have this paper where I have to...

I am only familiar with one mob, the one at the jail where
Tom Robinson is being held.  Atticus knows something is up, and stakes himself out there
with his newspaper, waiting for them to arrive.  Walter Cunningham's father, who owes
Atticus money he cannot pay, is among those men in the mob.  It is very interesting,
because when Jem and Scout come along, Scout innocently begins a conversation with Mr.
Cunningham about his son, Walter, and his "entailment" (his debt to Atticus).  This is
enough to remind Mr. Cunningham that he is in a mob that is threatening someone who has
been very good to him (and to his son).  Her innocent inquiries ("How's your entailment
comin' along?") are enough to diffuse Mr. Cunningham, who then disperses the rest of the
crowd and the crisis is averted.
