I assume since the pool accident has been stated, that JB is trying to maintain that Casey is not guilty of anything except for lying to Law Enforcement, which she already served time for. I believe AZlawyer said the cover-up would be considered obstruction of justice, yet she is not being charged with obstruction of justice. I don't recall anything in JB's opening statement that implied or stated how he is going to explain why the police was not called right after the alleged accident or where Caylee was put after the accident....yet both of these elements would be considered obstruction of justice, right? The pool accident theory might add a bit of reasonable doubt to get the jury to find her not guilty of murder, but can they vote her guilty for obstruction of justice if she has not been charged with it? I would think if the jury buys the pool story they would want to go with at least obstruction of justice. How come she isn't being charged with obstruction of justice, anyway?
