Final answer:
A person may indeed become a trespasser by not leaving when asked to do so by a Security Guard, as the guard has authority to maintain the order and safety of the property they are responsible for.
Step-by-step explanation:
True, a person may become a trespasser by refusing to leave immediately when ordered to do so by a Security Guard on duty at a site. Like the interaction between a citizen and a police officer, people must adhere to the authority presented by security personnel within their jurisdiction. If a security guard asks someone to leave the property, and that person refuses, they are disobeying the lawful request of the guard, whose responsibility is to maintain the safety and order of the site.
Just as a police officer has the power to enforce laws, such as issuing a speeding ticket, a security guard has the authority to protect property from unauthorized access or behavior. However, the extent of this authority has limits, similar to how a police officer cannot command personal favors like mowing a lawn. The security guard's authority is confined to their duty to secure the premises for which they are responsible.
