A more thorough explanation:

A peace officer is a civil officer appointed by public authority to maintain public tranquility and order. This can include police officers, sheriffs, and other law enforcement officials who are responsible for keeping the peace and arresting individuals who are guilty or suspected of committing a crime.

For example, a police officer who responds to a disturbance call and intervenes to prevent a fight from escalating is acting as a peace officer. Similarly, a sheriff who patrols a county to ensure that laws are being followed and public safety is maintained is also a peace officer.

In some cases, a judge who hears criminal cases or a mayor who is designated as a peace officer for limited purposes may also be considered a peace officer.

Overall, peace officers play a critical role in maintaining law and order in society and ensuring that individuals are held accountable for their actions.
