In 1963, Martin Luther King Jr. was arrested and sent to jail because he and others were protesting the treatment of blacks in Birmingham, Alabama. Over a thousand other people were arrested as well, and, as the jails and holding areas filled with arrested students, the Birmingham Police Department, led by Eugene "Bull" Connor, used high pressure water hoses and police attack dogs on the children and adult bystanders. A court had ordered that King could not hold protests in Birmingham. While locked up in jail,  he writes a letter which later on becomes renown as the "Letter from Birmingham Jail," arguing that individuals have the moral duty to disobey unjust laws.
