What are common signs of suspicious behavior?

Avoiding eye contact and being overly nervous are indeed common signs of suspicious behavior. Individuals who are potentially engaging in nefarious activities may exhibit anxiety through their body language, such as fidgeting or reluctance to make eye contact, which can signal that they are aware they are doing something wrong or are feeling guilty. This nervousness may stem from fear of detection or confrontation, making it a red flag for security personnel or observers.

In contrast, behaviors such as engaging openly with others or laughing loudly are generally not indicators of suspicious behavior. These actions tend to reflect comfort or social engagement rather than unease. Similarity, carrying multiple items without purpose might raise questions but does not strongly indicate suspicious intent without further context. It is important to consider the combination of behaviors and the context in which they occur to assess suspicious behavior accurately.
