Miller's, a department store, had experienced a growing incidence of shoplifting. At the store's request, the police concealed Best, a woman who was a detective, at a vantage point above the women's apparel fitting rooms where she could see into these rooms, where customers tried on clothes. Detective Best saw Davis enter a fitting room, stuff a dress into her pocketbook, leave the fitting room, and start for the street door. By prearranged signal, Best notified another police officer near the door, who detained Davis as Davis started to go out into the street. Davis was placed under arrest, and the dress was retrieved from her purse. Davis is charged with shoplifting. Her motion to prevent the introduction of the dress into evidence will be 
granted, because the police should have secured a search warrant to search her bag.  granted, because a customer has a reasonable expectation of privacy while using a department store fitting room.  denied, because the search and seizure were made incident to a valid arrest based on probable cause.  denied, because Detective Best could see into the room and thus Davis's activities were legitimately in plain view.
