Why might someone exhibit nervous movements?

Exhibiting nervous movements can often be associated with underlying anxiety or discomfort in a given situation. These movements may indicate that a person feels threatened or is in a high-stress environment, which can be common when someone is involved in criminal activity. This behavior might manifest as fidgeting, avoiding eye contact, or other signs of distress. Such nervousness can serve as a cue for security personnel to pay closer attention to the individual's actions and demeanor.

In contrast, excitement about a new opportunity typically leads to positive body language, such as enthusiasm and eagerness, rather than nervousness. Normal social behavior generally involves relaxed movements and can include gestures that foster communication, which are not indicative of nervousness. Feeling comfortable in an environment typically leads to at-ease behavior, contrasting with the signs of nervous movements. Understanding the context of these behaviors is crucial for security professionals when assessing a situation.
