What is the current state of the law in the context of consent under the Fourth Amendment?

⁷ Even when only a single governmental entity is involvedand not two, as was the case here, "[t]he standard for measuring the scope of a suspect's consent under the Fourth Amendment is that of objective reasonablenesswhat would the typical reasonable person have understood by the exchange between the officer and the suspect?" (Florida v. Jimeno, 500 U.S. 248, 251, 111 S.Ct. 1801, 114 L.Ed.2d 297 [1991] [holding that a criminal suspect's consent for police to search his vehicle did not constitute consent for police to search a bag within the vehicle that could not reasonably have contained the object police were searching for] ).
