going to jail was was her public relations people wanted... because she wasn't in the spotlight as much anymore. Furthermore, they knew that she would cause a commotion and try to get some people on her side which would get her some air time (doesn't she have anotheR POS show coming out again?)
Next, we all know that theres no way Arnold is going to pardon Paris... he saw the sex tape, and obviously wasn't impressed at her inability to even notice anybody in the room but herself.
Not to mention, we're practically guaranteed a Paris in Prison sex tape with her and some other hollywood hoe bag who got locked up for DUI. So just wait it out... she'll be fine. Hell, Martha went to jail for a lil bit.
