Final answer:
Dr. King uses the example of Hitler's actions in Germany to emphasize the difference between legality and morality in 'Letter from a Birmingham Jail'.
Step-by-step explanation:
In 'Letter from a Birmingham Jail', Dr. King reminds readers that 'everything Adolf Hitler did in Germany was 'legal''. This statement is a powerful rhetorical device used by Dr. King to highlight the discrepancy between laws that are unjust and morally wrong. By referencing Hitler and the legality of his actions, Dr. King implies that just because something is legal does not make it right or ethical.
In the context of the civil rights movement, Dr. King is drawing attention to the fact that segregation and discrimination were also legal in the United States at the time. He is urging individuals to question the morality and justice of these laws, and to take a stand for equality and justice.
