What was the name of the system used for law enforcement that protected citizens at all hours?

The term "Watch and Ward" refers to an early system of law enforcement characterized by individuals who were responsible for patrolling designated areas to ensure safety and order throughout the night. This approach originated in medieval England, where members of the community, often volunteers, would keep watch to deter crime and protect citizens during nighttime hours. The concept was essential for maintaining public safety when organized police forces were not yet in existence.

In contrast, the other options do not represent historical systems specifically tied to the concept of continuous protection in the same way. "Patrol and Response," "Guard and Shield," and "Shield and Protect" may suggest protective services but do not carry the same historical significance or established role in law enforcement as "Watch and Ward." The latter uniquely captures the essence of a vigilant community effort to safeguard residents, particularly during times of lower visibility and increased vulnerability.
