Firstly its is speculation that she drove around with the body in the trunk, unless you can tell me where in the docs it states unequivically that there was caylees decomp in there.(i've read them all , and know its not there).
IMO, She's not protecting anyone but herself and her poor choices that could have led to caylees death.(neglect, not being attentive and always watchful of where caylee was).
She's a pathalogical liar....never liked to admit her many faults and did everything in her power to protect her secrets....long before caylee went missing, and even before caylees birth, although it was clearly escalating over the years.
i have already stated that if it wasnt kc (and I certainly havent eliminated her, since I've posted many theories on how she could have done this), then the SOD would be an SO.
Remember GA saying that Caylee could open the sliding door to their backyard by herself? If KC was upstairs, or busy online, caylee could have walked into the yard to play and was snatched by a lurking pedo. We know SO's stake out houses, and focus on the ones with childrens toys, of which their where many in their yard. The location was ideal, since their are no houses behind the A home and it is isolated. (see my post from few days ago re: the SO who lives opposite the school and could have accessed the house and the dump site without any witnesses through the woods). It could have even been one of this guys pedo pals.
The open sliding door would give the SO opportunity to enter the garage to collect the trash bags, duct tape and laundry bag etc.
So going with this scenario, lets say KC comes downstairs and finds Caylee missing...she does a quick search, tries to call CA and GA to see if they know where she is, but cant get through to them...and realises how much




she's gonna be in when they learn caylee has vanished on her watch.
So she goes into cover-up mode. Her priorty wasnt finding or protecting caylee, but protecting herself from the 'you're a bad mum and its all your fault' speech.
Alternatively, she could have found a dead caylee (at the hands of an SO) in the yard or garage, and did what she felt she had to do to avoid the judgement of her family and friends....Dump Caylee and give herself time to come up with a plausible story: ie the imaginary nanny that makes her look less culpable. ie: "she's someone I really trusted, and had never done anything to hurt Caylee before"
Look at the mcCaan case. They made poor choices that led to maddys abduction. But they werent like KC....they told the truth, and admitted their carelessness, and neglect because they cared more about their daughter than the critisism that they would get for sedating their kids and leaving them alone while they dined.
But KC is not like them, or many other people.
KC knew that even if she called 911 people would still blame her(particularly her family) since it was her neglect and immaturity that gave an SO opportunity to take caylee.
Lets not forget that KC is still lying about who caylees dad is. Her life and liberty are not at stake for that, but she continues the lie because thats just what she does, and always has.
