What is the purpose of cordoning in perimeter crowd control?

The purpose of cordoning in perimeter crowd control is to surround and isolate a problem area. This technique establishes a physical boundary that helps to manage the crowd's movement and behavior effectively. By creating a cordon, law enforcement can prevent individuals from entering or leaving designated areas, which is essential for ensuring the safety of both the public and officers. This isolation allows authorities to control access to sensitive locations, investigate incidents, or manage potentially dangerous situations without interference from the crowd.

The other options, while they may seem relevant, do not accurately represent the primary function of cordoning. Moving the crowd to a different location or redirecting traffic pertains more to dispersal strategies rather than isolation. Engaging in dialogue is a more communicative approach that doesn't apply to the physical barrier that cordoning entails. Ultimately, the goal of cordoning is to establish a secure perimeter that stabilizes the situation and allows for appropriate response measures.
