Duke lacrosse: Durham "justice"
If you are a cab driver who gave a ride to an indicted Duke lacrosse player, the Durham police will dust off a three year old misdemeanor warrant and haul you off to jail. They will also take the opportunity to see if you want to change your story. If you do not, they will make sure the press gets tipped off about your arrest. You will wait in jail until a friend posts your bond.
OTOH, if you are the daughter of Durham's police chief, you can be arrested for a serious felony (assault with a deadly weapon) and be released on unsecured bail into the custody of your mother. Even better, the police will fail to serve you with two critical summonses that are outstanding.
