With all respect to the prior poster, I don't believe it is the moral or ethical responsibility of the defense lawyers to keep Casey safe. I believe the opposite: that it is their moral obligation to step aside and let Casey experience the consequences of her own actions. She is the one who killed her child, whether accidentally or deliberately. She is the one who refused to take responsibility for her actions and refused to ever tell the truth about it. She believed that if she never admitted anything, she could never be proved guilty, and it turned out she was right. So let her pay the price of being right about that.
Some may say the defense team were the ones who threw her family under the bus, and without that she'd at least have her family to return to, but I would not agree with either point. She did not have to go along with the defense strategy. She could have got up on the stand and denied that her father and brother molested her, or that GA was there when Caylee died. Again, she declined to tell the truth, so that's on her as far as I'm concerned.
And I'm not too sure the Anthony's would take Casey back even if she hadn't dragged them through the mud. There's still the fact that she killed their granddaughter, led them along with lie after lie about it, and will probably never tell them the truth even after being acquitted. And now there's the additional fact that she'll likely never be able to support herself, and that having her home would bring the public down on them like a ton of bricks, making their lives even more miserable and downright unsafe. I don't really believe that they would ever take Casey back, at least not under conditions that would acceptable to Casey (such as unlimited financial support and no questions ever about Caylee).
Casey's defense team is standing in the way of karma, for their own benefit I think. I think they should get out of the way and let karma take its course with her.
