I CAN'T Wrap my head around this - cannot get to the point of believing that GA was lying about seeing KC and Caylee on the 16th. Yes, maybe CA and KC did have a fight on the night of the 15th, but if KC lived there, she could have just gone to her room, and since she was texting and talking with AL late into the night I truly believe that she may have begged him to let her come over with Caylee, to which AL said that KC could come but not Caylee.
Which she could not do - which set the plan in motion for the 16th.
Now - GA, with all his faults, lies and contradictions, did in fact state to the officers during his interview the following:
1. He smelled something not right in the car.
2. If something is found to implicate his daughter, please let him know so he can prepare his wife.
3. He told officers that something was not right that was going on with KC and he thought she had something that she was holding back.
I do not think that GA covered up, nor do I think he had anything to do with baby angel's murder.
I think that if you want to see the truth, you have to look back to the first few days and interviews with the A's.
Once information began being released to the media and became news, that's when the A's did a 180 - I can see CA screaming at GA about throwing their daughter under the bus - I think that's when the A's realized that the truth hurt their daughter, and began covering up and lying for her.
