Do you have a favorite child? Does this child act in similiar ways as KC has done in the past? Having given them a beautiful grandchild and according to CA something to the effect of best mistake KC ever made, imagine how you would feel. It is easy to say you would react differently but we don't know that. If GA were married to anyone, anyone other than CA he would be admitting KC did something unforgiveable but that he will not turn his back on her. CA makes that impossible for GA to do unless he breaks entirely from CA. They are all THEY have, each other. No real friends, family not supporting them. It is them against the world and they know it. It's a matter CA would like to keep private, just within the family but it is way too late for that. So just deny it was one of their own that did this terrible thing is easier than facing the truth. Once the trial is here it will hit CA like a brick wall. JMO but fact is, it is very sad for them.
On the various threads discussing the inner workings (from what we can gleen from observing the A's responses and behaviors over the past year) all of the points you make above have been gone over and discussed. They do not alter the fact that KC's parents are excusing the killer of their granddaughter (according to the vast majority of posters). In marriage we don't loose our individual responsibility to society. People disappoint one another all the time to various degrees but I can't imagine harboring a killer - even if it was a member of my own family. Boy do I hope and pray that situation is not in my future. I'm not suggesting the situation is easy for them but they have made it very hard to relate to them to the point that they are suspects in my mind.
When I was a kid, my dad made me own up to my mistakes. He didn't care if he hurt my feelings or if I didn't like him during those time periods that he had to come down on me. In other families where anything goes, the kids (now adults) have had a difficult time towing their own line imo. I cannot relate to your argument because, even though I do tend to wear my heart on my sleeve, I'm trying to look at the situation from the standpoint where an innocent child lost her life. That fact being the utmost tragedy and not the misguided psyches of the adults. I don't know why GA is so wrapped up in what CA says/does to the point he has no voice of his own. I used to promote my facticious "Stand up and be a man club" because I do think what men do in our world matters. Maybe it is because my dad tried to do the right thing and I respect and appreciate him so much now. I had a bit of a wayward side to me that, if not for him, who knows what trouble I could have gotten myself into. If a child of mine ends up being a criminal, it will break my heart and I will feel like I failed as it is my job to instill right from wrong and consequences into them. To be honest, I don't think I would have known how to do that when I was twenty years old. My Mom wasn't much older than that when she had me but, like she likes to say, "The world seemed different then." Even though she was young she did not promote lying (like CA seems to). Now I'm just rambling but, still, I'm out of compassion for the A's. If GA wants to, he can still stand up and be a man and tell the truth and nothing but the truth despite what CA wants - she has the same responsibility to do so imo.
If, on the outside chance, it turns out that a third party is responsible for Caylee's death (many peeps are thinking figure the odds Woe), I will be the first in line eating my words and apologizing for all my hurtful speculation and mean spirited observations because then, and only then, could I ever begin to understand any of the behaviors the A's, collective or singular, have exhibited.
We are judged as individuals which is why we say to our teenagers things like it doesn't matter what Johnny gets to do, you're my child. Or, if so and so jumps off the bridge are you going to follow? Or, leave the scene immediately if someone is doing something that you know is wrong because to stay is to become an accomplice. One can only hope these messages are sinking in those thick skulls of theirs. To continue to excuse the wrongdoing of your child though is asking for big trouble as we are witnessing by following this case. Yes, I would feel guilty.
