What might constitute reasonable suspicion for law enforcement?

The correct choice is rooted in the concept of reasonable suspicion, which law enforcement officers need to justify a stop or brief detention of an individual. Observing behaviors that indicate possible criminal activity, such as criminal behavior, evasive actions, or flight when law enforcement arrives, can create a reasonable basis for suspicion. These actions suggest that the individual may be engaged in criminal activity or might be trying to evade law enforcement, which justifies further investigation.

In contrast, hesitation in answering questions may not provide a reliable indicator of wrongdoing; people's responses can vary for numerous reasons unrelated to criminal behavior. Being in an area with a high crime rate may raise a general concern but does not alone establish reasonable suspicion for any particular individual. Lastly, a previous criminal record could provide context but does not in itself justify immediate suspicion without current grounds for concern. Thus, it is the specific behaviors observed in the moment that form a solid foundation for reasonable suspicion and enable law enforcement to act accordingly.
