To use these 'explanations', ICA will either have to admit she killed Caylee or allowed an accident to go unreported.
It only explains her behaviour during the 31 days.
ICA would need to explain what happened on Day ONE, and I don't think she'll be taking the stand to help us understand/explain anything.
JB can't have an 'Ah Ha moment without ICAs version of events, so it's not likely to happen.
The defense has a Lot to quash right away and offer some alternative explanation that is plausible. There are some fundamental issues that must be addressed for the jurors or the defense will never stand a chance (IMO)
1) 31 days of not reporting
2) how the death happened
3) how Caylee's remains ended up 15 houses away with items from the home.
4) kc's partying and not grieving or being frantic during the 31 days
5) lying, stealing, and avoiding anyone who had authority over her (ie: school, work, parents, law enforcement, even Caylee's paternal bio-family).
6) the duct tape
7) the smell in the car
8) the outline of a child in her trunk
9) the death band on the hair
10) the sticker on the duct tape
11) no shoes on Caylee (I think this is an important clue to her demise)
12) not telling a single soul about her missing baby girl
13) not moving in with Amy, not taking over the house, not parents getting divorced . . .
14) NO ZTN!!!
the list continues . . .
