This is a circumstantial case as are most- there is layer after layer after layer that show, after looking at them, there’s no where else to go but that Caylee killed her daughter and told one desperate lie after another to hide it from everyone. “Conciousness of guilt”...
You may be right - but would you kill someone based on your belief? Pull out a knife, and slit her throat, and watch her bleed out like a goat?
I would not. Case not proven.
