An officer suspects that Mary is selling drugs out of her home. When the officer knocks on the door, Mary's husband, John, answers the door, and the officer asks permission to search their home. Which circumstance would be a violation of Mary's Fourth Amendment right?
John gives consent, but Mary immediately comes to the door and refuses permission. The officer continues the search regardless.
John tells the officer Mary is at work, and refuses permission for the officer to search. Because Mary isn't present, the officer searches the apartment regardless.
John tells the officer that Mary is at her parent's house, and gives him permission to search the apartment.
John gives consent to search the apartment, and although Mary did not want the search to continue, she does not protest because she is afraid she will look guilty.
