I don't know this person, have just looked up her work and don't think I've seen any of it.
I feel sorry for any victim of abuse, I was one myself so I therefore feel for this lady. We cannot know how troubled she was and how that really affected her and I hope she is now at peace. However, it was her choice to take cocaine and then drive. Presumably she could have afforded a taxi or even to have a driver, then she would be free to take cocaine and still be safe. It was pure luck that thank goodness she didn't take anybody with her.
I feel desperately sorry for her children who will have to deal with the pain of losing their mother and the fallout of her actions.
What I do find interesting and slightly hypocritical is that there was a poster on here recently who had got several speeding tickets and was worried about losing her licence. She had her backside handed to her and people were much harsher than they are being to this celebrity, telling her she could have killed someone etc and hoping she did lose her licence and any subsequent loss of her job because she deserved it.
