A more thorough explanation:

Definition: With all deliberate speed means to act as quickly as possible while still maintaining law and order and considering the welfare of the people. This term is often used in reference to the desegregation of public schools.

Example: In the landmark case Brown v. Board of Education, the Supreme Court ordered that public schools be desegregated "with all deliberate speed." This meant that schools needed to integrate as quickly as possible while still ensuring that the process was done in a way that maintained order and protected the well-being of all students.

Explanation: The example illustrates how "with all deliberate speed" was used in the context of desegregating public schools. The Supreme Court recognized the urgency of the situation but also acknowledged the need to proceed carefully and thoughtfully to ensure a smooth transition. The term emphasizes the importance of balancing speed with caution and consideration for all parties involved.
