First and foremost, King establishes his credibility to spark off his strong defense. Introducing himself as "The President of the Southern Christian Leadership Conference, an organization operating in every southern state, with headquarters in Atlanta, Georgia. â€¦ [with] eighty-five affiliated organizations across the South, and one of them is the Alabama Christian Movement for Human Rights" ("Letter from Birmingham Jail" 2). This credential not only puts King into a position of power but also proves that he has seen enough of the south and the problems within it to create a strong argument against his opposition. Another point that establishes this is on page seven of "Letter From Birmingham Jail" where King states that he's traveled through the "length and breadth of Alabama, Mississippi, and all the other southern states. On sweltering summer days and crisp autumn mornings". This quote defends his credibility further because not only did King travel once through these states but multiple times in different seasons, and even deeper- in different trials that may have been presented. Moreover, throughout the letter, King references the Bible, presidents, and writers to establish not only his educated mind, but also his passion for righteousness and his stance as a minister. The flawless flow of his passionate response to the Clergymen also presents support for his intellect and knowledge due to keeping a reasonable head and developed grammar while inhabiting a jail cell.
