I don't know if I should do this, but here it goes:
I believe 99.9% that Casey murdered her baby intentionally. But, if I were a juror, here are some things that might tug at that .1% in me and possibly give me reasonable doubt (God and Caylee please forgive me for this):
-Have Casey either cut her hair shoulder-length hair and style it like a typical housewife, with a head-band (my personal style, lol), or some hair-clips on the sides. This may not be possible because these items might be considered weapons if she had access to them.
At the very least, get a short, soft cut. Casey has very peculiar features and the long-style makes her look a little like the Manson girls before they shaved their heads.
-Dress her in Sunday-type casual dresses, instead of creepy, two-piece ensembles.
-STOP with the taking notes. Tell her to look a little sad from time to time. No more cavorting with and that crazy-looking giggling with her defense team.
-Put her on the stand. You have to shock the jurors with something and this might be it.
-Have her say that Caylee drowned while Casey was on the computer. She lost track of her child in an instant, hence the 'flurry' of phone calls. Have her cry her eyes out when she talks about this scenario.
She has to convince them that this was the reason she was frantically looking for her parents - she was not calling about a dead baby, just about a missing one.
-Tell her to explain that she came up with the babysitter thing when she found and couldn't revive Caylee. Lots of tears and requests for water and breaks here...
-Make sure she explains about how she re-dressed Caylee and disposed of the original clothes somewhere ("They haven't even found her clothes yet...")
-Tell her to make-believe to the jury that she duct-taped the baby so that, if the body was ever found, it would look like a kidnapping-gone-wrong.
-Explain to a jury that the chloroform in the trunk was caused by evaporating chlorine in Caylee's little body, mixed with decomp chemicals.
-Have her cry about the fact that she was, after all, a little relieved by the absence of Caylee and that she was deathly afraid of her over-bearing mother and her child-molesting father. So, she will say, the only thing she could do was hide out and party, pretending nothing ever happened.
-Tell her to explain how she convinced herself that Caylee was in a better place, 'close to home,' until the decomp smell caused her to take further action.
-Act like this is all news to the DT and that, at the last minute, Casey wanted to come clean. This will shock the heck out of those 12 good men and women.
Honestly, if you get a jury who knows very little about this case, I am certain you will be able to build reasonable doubt among a few of the members, at least for the Murder 1 charges.
Again, God help me...
