Well, she herself admitted that she did lie and said that she "didn't know why". It seems quite obvious, to me at least, that since she has told numerous opposing stories about what went on that night that ALL of them can not be true. NONE of them may be true at all, but at least some of them have to be lies since the stories are completely different and can not possibly all have happened. For example, how is it possible that it is true that she put Haleigh to bed at 8, then at 8:30 or 9, then at 10:00 and then "after she watched two movies" which were not put into the VCR until after 8 p.m.? How is it possible that Haleigh and JR. watched those two movies together in bed, yet one of them was put into the living room VCR for Jr. after an argument between the kids? Well, you are smart, so you get the point. There are a multitude of other examples but they have been reiterated endlessly already.
