Because today the whole world media will be broadcasting their words and it will not be possible to ignore what they have to say.
I don't know if speaking while grieving, and after having to listen to that scumbag Felos, is going to accomplish anything good - the media will be provoking outrageous comments, and THAT is what teh world will hear unfortunately.
I just don't see how going out to face the media so soon after her death can be considered a good thing by any stretch...
