What are common signs of suspicious behavior?

Loitering and repeatedly checking one's surroundings are significant indicators of suspicious behavior for several reasons. When individuals loiter in an area without a clear purpose, they may be waiting for an opportunity to commit a crime or engage in behavior that is not typical for the setting. This lack of purpose can raise concerns for security personnel and those responsible for safety.

Additionally, repeatedly checking one's surroundings suggests that a person is either feeling anxious or is being overly cautious, which might imply they are aware of their actions being potentially inappropriate or unlawful. Such behavior diverges from normal conduct, particularly in environments where the expectation is to engage in activities for a defined purpose—like shopping, working, or visiting.

The presence of individuals following security personnel can suggest an intention to distract or intimidate, and while it may be considered suspicious, it does not universally indicate nefarious activity. Excessive talking with others can occur in many contexts and does not inherently point to suspicious behavior. Wearing sunglasses at night, while potentially odd, does not serve as a reliable sign of suspicious intentions compared to the more overt behaviors of loitering and vigilant scanning of surroundings.
