Step-by-step explanation:
The instruction that should be used to train the security force in the use of deadly force is the legal framework surrounding the use of force. It is important for security personnel to be thoroughly educated on the laws and regulations that govern the use of deadly force to ensure that it is used appropriately and within the boundaries of the law.
Training should include topics such as the circumstances under which deadly force may be used, the proportionality of force, and the duty to retreat when possible. Role-playing scenarios and case studies can also be utilized to help security personnel understand how to make split-second decisions in high-stress situations.
Ultimately, the goal of the training is to equip security personnel with the knowledge and skills to effectively assess threats, make informed decisions, and use deadly force as a last resort, only when necessary to protect themselves or others.
