Explain how and under what circumstances the three major exceptions to the exclusionary rule of the Fourth Amendment operate. Give an example of each exception.
One night Tiffany borrowed a friend's car so that she and her girlfriend, Heather, could get to their jobs at the hotel where they worked in the cocktail-bar section of the restaurant. In order to be able to stay awake and alert on their shift at the restaurant, the two college women took some amphetamine tablets that they got from their boyfriends at the local law school. While the two women were motoring toward the restaurant, for no valid reason, a police officer stopped the pair just to check them out and inquire where they were going. The officer seemed to have an extra interest in Tiffany, the driver. He decided to search the interior of the car and found the bottle of amphetamine pills in the glove box of the car near where Heather had been sitting. The women explained how the car did not belong to them and that Tiffany had borrowed it from a friend. After their respective arrests, the officers found recreational amounts of marijuana in the purses of both women. Tiffany and Heather are hopeful that all the evidence of drug possession can be excluded from admission in evidence due to a Fourth Amendment violation.
