That really doesn't have much to do with the situation though. According to all reports she could have just walked out the door, his kids were there and he was not forcefully keeping her in the house or, the key point of stand your ground, threatening her life or putting her in immediate danger.
That's all fine if you want to argue that. I just have a problem with people continuously saying she left the house or that she was already out of the situation every time the topic comes up. When the first is not true and the second is not a fact.
