Which of the following elements contributes to reasonable suspicion in law enforcement?

The correct choice is based on the idea that reasonable suspicion in law enforcement is grounded in factual circumstances and observable behavior that suggests criminal activity may be afoot. Traffic violations can be a clear indication of a potential crime, and information obtained from a third party can provide additional context that raises suspicions about a person's behavior or intentions.

When an officer observes a traffic violation, it may not only violate traffic laws but can also indicate reckless behavior or evasiveness that raises concerns. Third-party information, such as a reliable tip-off from a witness, can provide corroborative evidence that further enhances an officer's suspicions. Both of these elements work together to create a basis for reasonable suspicion, which allows law enforcement to engage a person for further questioning or investigation.

Factors such as conducting random stops do not typically establish reasonable suspicion, since they lack an individualized basis. Visible signs of distress may contribute to a broader assessment of a situation but cannot solely establish suspicion without further indicators of criminal activity. Additionally, personal opinions of the officer can be subjective and often do not meet the objective standard required for reasonable suspicion within the framework of law enforcement practices.
