I think everyone is being hard on her family and want to assume that she had a "messed up" childhood. However, after listening to more and more videos of her parents and brother, I think they seem very normal and nice in fact. I truly feel that Casey was immature and angry and self-serving. Why? I have no idea, but my opinion of her family is not what some are automatically assuming.
Remember how Casey broke down on the stand when Lee was speaking? I also saw a picture on line (from her original Facebook pictures) where she was hugging her brother and the picture was titled, "The best brother in the world!". Some thought of Lee's tears on the stand as being "creepy"....I think he is in sooooo much pain!! Casey lied when she said that she didn't allow Caylee to be around him....there's a lot of pictures of him holding and playing with her. Just another lie of hers.
