Final answer:
Law enforcement tactical units are responsible for establishing a command post and outer perimeter in hostage/barricaded suspect situations, coordinating response efforts, and securing affected areas.
Step-by-step explanation:
During a hostage/barricaded suspect situation, the law enforcement officers, specifically SWAT (Special Weapons and Tactics) teams or similar tactical units, will be responsible for establishing a command post and an outer perimeter.
The command post functions as the central hub for command, control, and communication during the response to the incident. It is typically managed by senior officers who coordinate the various aspects of the incident response, including intelligence gathering, negotiation efforts, and tactical operations. The outer perimeter secures the area surrounding the incident to contain the threat, prevent unauthorized entry, and protect bystanders and neighboring areas from potential harm. This perimeter is usually established by patrol officers and can be reinforced by additional law enforcement personnel if necessary.
