I can only imagine that prison, even a county jail, can't be fun for anyone. And Paris Hilton is probably particularly ill-equpped for that kind of not-fun thing. But it seems pretty obvious that she a) exhausted all her second (and third) chances for leniency, and b) should serve her time, like anyone else would. But who thinks otherwise? Apparently a sheriff, and you have to wonder what persuaded him. Maybe this experience will help her grow up. Or maybe she'll think of herself as a victim and won't learn a thing.
