Final answer:
The Birmingham official was Bull Connor, who ordered violent actions against Civil Rights protestors, leading to the arrest of Martin Luther King Jr., who then wrote 'Letter from a Birmingham Jail.'
Step-by-step explanation:
The Birmingham official who dealt violently with the Civil Rights protestors was the police commissioner Bull Connor. During the Birmingham campaign of 1963, Connor ordered police to use fire hoses and police dogs against peaceful protestors, including children. This response was televised, showing images of brutality that galvanized support for the Civil Rights Movement. Notably, Martin Luther King Jr. was arrested during these demonstrations and wrote the seminal "Letter from a Birmingham Jail," where he argued against the calls for patience from white clergymen and made a case for the immediate need for justice and civil right.
