What should a security guard do upon seeing a male smoking marijuana outside a mall?

Choosing the option that states you have no authority to arrest for or seize the drugs and suggesting to ask the male to leave the premises for the prohibited activity is correct because security guards generally do not have the legal authority to make arrests or seize illegal substances.

Instead, the role of a security guard is to maintain safety and enforce policies within a property while adhering to the legal limitations of their position. In many jurisdictions, smoking marijuana can be a violation of property rules, particularly in public areas like a mall. Therefore, by asking the individual to leave the property, the security guard is performing their duty to uphold the mall's policies without overstepping their legal boundaries. This reflects a balanced approach to managing the situation, prioritizing safety and compliance with the law without assuming law enforcement powers, which are beyond their scope of responsibility.
