While I agree with your opinion of her possible level of emotional development, I strongly disagree with you about her possible retardation. Heck, I'll write off the possibility of mild retardation.
Forget her family's vast fortune. She's simply a spoiled brat. There are many like her, male and female, around the world, who don't necessarily have as many zero's attached to their bank account as hers. It's not her fault that she's a spoiled brat. Lay that at her parents' feet.
From what little I have followed of her life, it wouldn't surprise me at all that she ends up in legal trouble again at some point. Her reactions radiate an air of, "I'm going to do what I want to do, so there!" The young woman has done "reality tv"
, plays extremely to the cameras whenever possible (examples: caught dancing on tables, attempting to ride motorcycles without an previous training in a crowd of people, wearing the shortest skirts possible knowing full well that she doesn't have any panties on, etc.) and has knowingly created and distributed a sex tape.
The young woman knows what's she's doing. She ain't stupid. Let her reap what she sows.
