Who does Billy Ray Cobb's brother, Freddie, approach in seeking revenge, and what is the result?

Freddie Cobb, Billy Ray's brother, approaches the Ku Klux Klan at a meeting they are having in Nettles County, just over 200 miles south of Ford County. Mississippi Imperial Wizard Stump Sisson is in attendance, and Freddie requests assistance in obtaining revenge for his brother's murder . He is told by gaining five or six new members and joining the KKK himself, they will consider his request. In fact, they view this as a good opportunity to take advantage of recruiting new members and generating hatred of black citizens.
