When is the phrase 'in pursuit' commonly used?

The phrase 'in pursuit' is commonly used when law enforcement officers are actively chasing a suspect who is fleeing from a scene. This situation typically involves an immediate need for officers to engage in a high-speed chase or follow a suspect on foot, indicating urgency and a need for quick action. The term underscores the dynamic and potentially dangerous nature of pursuing a suspect who is attempting to evade arrest or capture.

In contrast, other scenarios like traffic stops, routine patrols, or traffic safety checks do not usually involve the urgency or immediacy associated with the concept of pursuit. Traffic stops are more about interaction with drivers for violations, routine patrols focus on general observation and community safety without a direct engagement with suspects, and traffic safety checks are preventive measures to ensure compliance with laws rather than active encouragement of fleeing individuals.
