No clobbering here. I just happen to think of it differently. Based on ICA's personality, an accidental drowning would have been perfect. Casey would get sympathy, the child would be gone, she (casey) would get all the attention and pity, yet have the freedom to live the Bella Vita. She could have played it to the hilt. Calling 9-1-1 in hysterics, having a dramatic funeral, on and on and on....
That is precisely why I DON'T think caylee drowned. Whatever caused caylee's death would be easily discovered, and that's why casey had to cover it up.
It was NOT innocent in any way, IMO.
Edited to Add: if she wanted to make sure caylee was really dead after the drowning, why not hold her under water for longer, why go to the garage and get 3 or 4 pieces of duct tape? Just doesn't make sense to me, IMO. But with this case, who knows.
