In my opinion, the reasonable doubt is only to premeditation. If the state can't prove that Casey was the one that looked up chloroform, premeditation is likely out the window. I am fine with that because I never thought Casey chloroformed Caylee to begin with. I thought that was all for her own pleasure. I also never believed Casey would get the death penalty so no biggie there for me. I don't think reasonable doubt applies yet to the actual murder.
My anger is that Cindy clearly knew what Baez was going to ask her and she was prepared. That tells me she will do anything for her daughter.
