Not that I expect anyone to answer this objectively, but take your personal thoughts of her out of this. Do you really think what she did is worth 45 days in jail?
The DUI, sure - but it was probation for that. But, 45 days in jail for driving without a license? If it wasn't Paris Hilton, doesn't anyone think that sentence would be a little harsh? Take her name out of it, and see if you wouldn't think it's going overboard.
And I know her, and celebrities get away with a sickening amount for just being famous - but I'm just talking about this case.
