I can take a guess on what they are going to say in the courtroom to make us sit back and say, "That explains it . . .. "
The story is going to go like this:
Z stole the child in June. Told Casey that if she contacted the police, parents, etc, she would not only harm Caylee -- but would harm her family also.
This is why they are saying, "Casey will look like a hero." By doing this -- Casey not only saved Caylee from getting hurt -- but she also saved her family from being kidnapped / hurt also.
Unfortunately -- most of us live in reality. I doubt "Z" told Casey to go to a hot body contest, steal checks, etc.
Of course -- if this was the "true scenario" -- they could have told this to LE already.
Seeing we already know their defense, and it's a complete sack of crap, what's next? Is that the best they could come up with? If that is their story -- might want to start firing up "Old Sparky"
