For what reason must security guards understand their limits and responsibilities?

Understanding their limits and responsibilities is crucial for security guards primarily to avoid liability for actions outside their scope. This knowledge ensures that security personnel operate within the legal framework and adhere to the duties assigned to them, which protects both themselves and their employers from legal repercussions. When guards exceed their defined authority, they not only risk personal liability but also jeopardize the safety and security of the environment they are tasked to protect. Recognizing the boundaries of their role helps maintain professionalism and keeps the focus on their primary responsibilities, ensuring effective and lawful conduct in their duties.
