I see how that could be argued but I don't think that is a sure bet.
For instance, her answer to that first question can be affirmative. Quick short answer. Yes, I'll admit that.
But the longer answer which she will likey not say since you don't answer more that the precise question would be, but on the other hand, why would I have seen or observed that call or even been convinced he should make it? I was in shock, he was telling me that "Daddy would handle things" and left with Caylee. I then left and had no idea for weeks what he had done and still didn't know until her remains were found that she was deceased. (that would in a way fall in line with the garbage she told those two doctors in the depositions).
Remember we can only hold her to what she, herself, has said. She can not legally be held to what her attorney said in his OS. She could just outright say today that he did not tell her true, full side of it and what she told the doctors is what she told him. He just modified it on his own without her knowing he was going to do that.
IMO
Now, the 2nd question can be answered, yes she knew they were searching but then if she sticks to her other story that she had no idea until the remains were found what had really happened, she is still off on that 2nd question as well.
