At this point GA would be fully justified in throwing ICA under the bus the next time he takes the stand. I sure would love to see that.
I would look at it as a form of self-preservation and protecting the family I had left. That little monster ruins everything she touches. I have to wonder... if she got LWOP would her lying and manipulation eventually get her high in the pecking order with other inmates, kind of taking over, or would jailhouse justice quickly find her? She is supremely manipulative and deceptive, and I really think she needs to die to not only provide justice for Caylee but to protect others.
BBM - Well (IMO) from what Lippman is quoted as saying looks to me in this article that (bolded section above) is the plan now if the defense continues down this path of destroy GA at all costs.
