Under what condition can a frisk search be extended to the "grab area"?

A frisk search can be extended to the "grab area" when there is reasonable suspicion that the person may be armed, making option B the correct answer. This principle stems from the need to ensure the safety of law enforcement officers during a stop. A frisk, which is a limited pat-down of the outer clothing, is based on the officer's belief that the individual may be carrying a weapon.

If the officer has reasonable suspicion that a weapon is present, the officer has the legal justification to extend the search to areas within reach where a weapon could be concealed, known as the grab area. This is supported by case law, where courts have determined that concerns for officer safety necessitate a search of areas where a suspect could access a weapon.

Other conditions related to consent, necessity, or if an object appears dangerous may not provide the specific legal backing required to extend a frisk to the grab area as effectively as reasonable suspicion of a weapon does. Thus, while those scenarios may justify some form of search or inquiry, they do not carry the same legal precedence as reasonable suspicion concerning the immediate danger of weapons.
