Which statement regarding lawful searches is FALSE?

The statement about consent allowing a search of the entire property is false because consent is limited to the areas where the consenting party has authority and can reasonably expect to exercise control. If a person allows law enforcement to search their premises, this consent does not automatically extend to all areas of the property unless explicitly agreed upon.

For instance, if someone allows a search of their living room, this does not imply permission to search private areas such as a bedroom or a safe without further consent. In practice, if law enforcement intends to search multiple areas or items, they should seek specific consent for each location or item to ensure the legality of their actions. This principle is rooted in the idea of reasonable expectation of privacy, which varies from area to area within a property.

The other statements reflect principles of lawful searches accurately. Emergency situations do justify warrantless searches to prevent imminent harm, a valid search by warrant does indeed require probable cause to obtain from a judge, and consent can be revoked at any time, thus ensuring individuals can assert their rights regarding searches.
