She really did not say anything much at all about the accident. At 1:30 to 1:40 of the video, the only thing she said "was that the LAPD still has an active investigation and I don't really have anything to add", and that her gut tells her it was a very tragic accident. That is all she said about the accident.
Very interesting to note, at 1:33 as she says "I really don't". Watch her mouth and lips grossly contort as she says those words. Her eyes betray something as well with her right eyebrow raising up. She I believe is pulling back on that answer. Her voice does show emotion and cracks when she said "I am very unlucky and the world was very unlucky".
The majority of the interview was chit chat about Michael and things. I think she was playing cover as she probably should at this point. There is still the issue of Michael being cremated without her permission, that would be a major issue for anyone. She is just playing heads up right now, it is quite obvious.
