Anatomy of a lynching

It is an academic (PhD work) that examines the last (?) lynching of an African American (Negro), which occurred in West Florida. The author observed that economic conditions; that is, competition for jobs in the lower economic classes of the day, contributed to conflict between the races. The lynching resulted from an alleged rape of a white female by a black male near Marianna, Fl. The male was jailed and carried to a "safe" place in a jail in Southern Alabama but was taken by a large mob of whites, who carried out the lynching. The book contain historical photos and accounts and is not for the faint hearted.
