well she made her bed and died in it. and probably is she would have not been American she would be still rotting in Jail - although I don't know if she is guilty
I know that for a non-experienced criminal the pressure cops push on you can lead to different versions, BUT she really made up so many stories. before her conviction she framed another guy who had nothing to do with the murder and almost got his life ruined, to then change story several times.
