She'll likely only spend a couple of hours (at the most, a couple of weeks) in jail as well. There's usually a big discrepancy between the sentencing and actual time served. But yes, she deserves it if everyone else in the exact same situation gets a similar sentence, which they do.
On the bright side, I'm looking forward to seeing her on Celebrity rehab with Dr. Drew very soon!
I agree, they should be treated the same as everyone else, I just don't like Paris much
