I believe she is guilty as hell! I also believe the prosecutor didn’t prove her guilt BEYOND A REASONABLE DOUBT. She will be judged by a much higher judge, as will we all, someday.
It's situations like these where I find great comfort in G-d and the afterlife. Casey has gotten away with it in this life, but she won't in the next. And I believe that what G-d dishes out will be far worse than anything we could do to her.
Caylee has peace now and she WILL have justice later.
