Why do you suppose police officers are advised to allow those whom they stop to engage in verbal venting?

a. Individuals who verbally vent have no legal standing to later complain that they were stopped inappropriately or illegally.
b. It is better to allow a person to express his or her frustration and anger than to allow it to escalate into physical action and violence.
c. Allowing a person to verbally vent provides the police officer another opportunity to write that person a citation.
d . Verbal venting is just a strategy to make the person who has been stopped look foolish to passersby.
