Personally, I think this is all a waste of time (a HUGE waste!
).
First, the prosecutors know what they can and can't ask witnesses at trial. They're not rookies, these are all experienced trial attorneys. They know how to ask a witness a question.
Second, the 911 call will most likely be heard. I seriously doubt that the judge will allow the bad acts of the defendant to determine what evidence is or is not admitted. According to the testimony of CA, the first time she heard that Caylee had been kidnapped was when the 911 call was made. The fact that KC didn't report her missing should not help her in any way, and I doubt that the judge will allow that to happen.
Third, the fact that there was a strong odor of decomposition in the car will be attested to by YM and other members of law enforcement, and the statements of GA made to YM during his interview. CA's statement is chilling, emotional, and makes me shudder to think about, but in the long run it's not all that important. Everything she says in her call is repeated and re-confirmed by others.
In addition, the comments that they are trying to have excluded about KC being a thief can be substantiated by KC's guilty pleas in her criminal case. She's a convicted felon and a proven liar, by her own words.
KC's statements about not seeing her child for 31 days were repeated to YM during the infamous trip to Universal. That will be admitted, so that tape is a tiny cog in this case. Personally I think YM and the rest of law enforcement did a great job locking KC into her lies. IIRC, she signed her statement stating when she had last seen Caylee, and I know she said it numerous times in interviews. She'll take the stand in that way, for sure! Maybe her butt won't be in the seat, but her words will be heard.
Much ado about nothing, and a HUGE show of cajones by JB to even try to get this past the judge.
