Bingo! That was my point exactly, although the Chloroform evidence may not have been as strong, this is not a CSI show, nor a videotape. The jurors should have been smart enough to put together all of the pieces that Casey, and Casey alone killed Caylee. The Essa Jury and the Peterson juries were able to connect the dots without all of the specifics, and the prosecution is not required to present the exact manner of death, it's obvious who killed her, and it wasn't accidental, nor were George or Roy Kronk ever involved- innocent men whose names were dragged through the mud!
The prosecution boiled it down into a pablum to spoon feed the jury. They still choked on it.
Now and then, with the nature of our justice system, we're gonna have a jury with just enough folks in it who can't or won't understand. Juries have convicted innocent people too, because they were infected with racism or bigotry of some sort or other.
