Demonstrate a critical thought process about below:

Acevedo settled the debate about containers inside vehicles that officers have prob- able cause to believe have contraband in them. But it didn't settle the privacy ideal balance when the containers are attached to people in the car, such as wallets in your pockets or in the purse hanging over your shoulder, or on the seat beside you. Recall that one of the reasons for the vehicle exception to the warrant requirement is a reduced expectation of privacy in vehicles. Do passengers as well as drivers have a reduced expectation of privacy? And, if they do, can officers search a passenger's purse when they have no probable cause to suspect her of the crime they arrested the driver for? In our next excerpt, Wyoming v. Houghton (1999), a divided SCOTUS interrogated that problem, again in an illegal drug case.
