What I'm about to type here probably won't be very popular, but please understand I am not trying to personally attack anyone. I'm new here, and I think what people do here is very interesting.
Although this case is unusual and the surrounding circumstances horrifying to many of us, I feel we all may tend to lash out against people involved, such as Caylee's grandparents, uncle or adult friends.
I would hate to think what people would say of me if my grieving process, my behavior in times of great stress, became national or international news. If the only side of me people ever saw was the side brought out in a time of great personal tragedy, I imagine they wouldn't like what they saw.
I think many of us can say that.
With that in mind, and knowing how awful this time in their lives must be for those close to Caylee, I would hope that we could be compassionate people.
Although I believe the discussion of motive, honesty, and behavior is appropriate to people searching for clues and trying to solve a case, calling people names or bashing them does not move the discussion in the appropriate direction.
This is just my opinion. I sincerely mean no harm to anyone.
