Which of the following is considered an indicator of a potential crime in progress?

Suspicious behavior or actions are key indicators of a potential crime in progress because they deviate from what is considered typical or expected in a given context. For example, if someone is seen lurking around a location without a clear purpose, behaving nervously, or attempting to conceal their actions, it raises red flags for security personnel. Trained observers know that recognizing unusual activities – such as someone trying to avoid being seen while moving in and out of dark areas or frequently looking over their shoulder – can be a sign that something is amiss, prompting further investigation or intervention.

In contrast, routine behavior of individuals often does not indicate any threat and can mislead an observer into thinking that everything is normal. Similarly, while a large crowd could create a chaotic environment, it does not inherently suggest criminal behavior without additional context. Public demonstrations can be peaceful and lawful expressions of opinion, which might not indicate a crime in progress unless they escalate to violence or unlawful conduct. Therefore, identifying suspicious behavior is crucial for maintaining safety and reacting promptly to potential threats.
