The best choice is when the situation escalates beyond their control, as this reflects a critical aspect of a security guard's responsibilities. Security guards are trained to handle various situations, but their primary goal is to maintain safety and order. If a confrontation with trespassers becomes aggressive or poses a threat to their safety or the safety of others, it becomes necessary to involve law enforcement.

Security guards should always assess the dynamics of a situation, and if they sense that it is moving towards violence or unpredictability, calling law enforcement is a wise and responsible decision. This ensures that trained professionals can handle the situation appropriately, minimizing the risk to everyone involved.

The other answer choices may offer insight but are less appropriate for determining when to call law enforcement. Simply feeling uncertain about authority does not justify immediate police involvement. A verbal warning is a standard protocol, but the situation could escalate before reaching that point. Lastly, while there are instances where law enforcement should be called regardless of the situation, it is generally wiser to evaluate the severity and context before making that decision.
