I just had a thought. KC is going to realize very quickly that she is NOT WELCOME anywhere in the US and as survival is all she cares about(as opposed to retribution or recovering), she is going to have to leave.
There is nowhere within the 50 states that she can go without being harrassed and as other sleuthers have said, if she stays, she better watch her back.
I won't tell you what I hope happens to her but it involves the ultimate Justice for Caylee. In lieu of that Jack Ruby type occurrence, I think she will make enough money with interviews to flee and then in fact escape to another country.
JB and CM will help her do this. They'll tell her that after a few years, she can return here because noone will remember her..but that would be to underestimate the memories of many people.
Oh, and in Mexico, the chances of her surviving very long would be minimal. So KC: do you like Mexican food?
