What is an indicator of a potentially dangerous situation?

Sudden movements in an area can signify a potentially dangerous situation because they may indicate an unexpected event or the presence of a threat. In many scenarios, rapid changes in behavior or activity levels can be precursors to violence or emergencies, prompting a need for heightened awareness and caution. For instance, a sudden rush of individuals away from a location may suggest an urgent threat that requires immediate attention.

Observing sudden movements compels a person to assess the environment closely, as these changes can disrupt the norm and signal that something is amiss. Being alert to such indicators can be crucial for self-defense and ensuring the safety of oneself and others in a given area.
