What does the associated code 10-31 refer to?

The code 10-31 is used to indicate suspicious activity. This term is important in police work as it alerts officers to the presence of behavior or situations that may warrant further investigation or increased attention. Officers are trained to observe and report any activities that appear unusual or out of the ordinary, which could potentially indicate criminal intent or a threat to public safety. Recognizing and responding to suspicious activity is a crucial part of proactive policing, as it allows law enforcement to prevent incidents before they escalate.

In contrast, the other options pertain to specific situations or directives that are more defined than the broader category of suspicious activity. The specific codes like "felony type hit" or "traffic check" refer to particular responses or checks that officers may perform, showcasing the relevance of specificity in communication amongst law enforcement.
