Which type of behavior might indicate to a security guard that illegal activity is occurring?

Suspicious actions such as loitering or attempting to evade security procedures serve as clear indicators to a security guard that illegal activity might be taking place. Loitering can suggest that an individual is lingering in a location without a legitimate purpose, which can often precede unlawful behavior. Furthermore, attempts to evade security measures—whether it be avoiding check-in points, bypassing established protocols, or otherwise trying to slip past monitoring activities—Signal a potential intention to engage in something illicit. These behaviors raise red flags, prompting security personnel to investigate further to ensure safety and compliance with laws and regulations.
