Problems:
Agreeing with you here:

One serious conflict of reason with apologias and defenses:
Why is KC so happy and fun-having?
Because she knows Caylee is safe with whomever has her.
Because this was a rage-vengeance murder aimed at Cindy and people who commit those types of murders are on a high afterwards! They are very happy about what they have done, imagine their problems are fixed forever and want to celebrate!
Why won't KC talk to LE?
Because she's too frightened of whomever has KC.
Because it does not benefit her. She knows she is guilty. Also, she is actually enjoying the power she has. EVERYONE wants to know what only SHE knows! In her mind she has become a celebrity! She even told Leonard Padilla something like "I didn't mean to become a celebrity!" and in addition, by not talking she is making her mother suffer all the more which is EXACTLY what Casey wants!
The ONLY scenario that makes sense is that KC is not grieving because she doesn't care about Caylee. KC is silent because she is genuinely afraid of prosecution, and for good reason.
I still think she let the child die accidentally, and was briefly panicked. However, once she figured out that her family would cover for her, I think she has enjoyed being an unencumbered young woman, again?
Look at the Logan Tucker case which is startlingly similar to the Caylee Anthony Case right down to the borrowed shovel:
Logan Tucker Case: 6 year old disappears, body never found, mother convicted of murder. Mother told a big pack of lies about his whereabouts - many of them just plain ridiculous.

She got rid of him because with him around she couldn't do what she wanted to do. She celebrated his demise by winning second place in a topless contest and hanging with her new boyfriend. Her son's body was never found. It took 6 years to bring her to trial on the murder charge. She was sentenced to life without parole.
