What situation would require a convoy or escort?

Providing security for a dignitary necessitates a convoy or escort due to the heightened risk associated with such individuals. Dignitaries, such as government officials or foreign leaders, often attract attention that could pose threats to their safety. As a result, law enforcement agencies implement protective measures during their transport to mitigate any risk of harm. This may involve coordinating a detailed escort that includes multiple vehicles to ensure the dignitary's safe arrival and demonstrating a visible presence of security.

In contrast, while transporting evidence and conducting community outreach can require careful planning and supervision, they typically do not entail the same level of security concerns that would mandate a convoy. Responding to a traffic accident also focuses on emergency response rather than protective measures for an individual. Therefore, the specific need associated with dignitaries justifies the requirement for an escort or convoy.
