I've watched pretty much all shows, documentaries etc Casey Anthony involved..I saw this documentary today and watched it.. I'm not sure if I socially want to say this.. but I'm going to anyone can disagree but I don't want hate responses from this.. But I'm actually believing that she didn't kill her daughter. Now I'm also a former Peace officer, also a mother, also a survivor of domestic violence and also a survivor of childhood sexual abuse.. which lead me into law enforcement. If you watch this 3 part series.. you will see when her dad and mom go to the jail, Mom is asking questions "Do you feel she's safe? Do you feel she's near? Do you feel she's ok?" Casey says yes to all.. meanwhile dad, behind mom... never looks at Casey... he's looking at his wife from behind like his eyes are cutting as if he wants her to stop asking. Then a visit after where it's just him and he says Caylee will be ok & they'll all be together soon.. I could go on... point is I believe Dad played a part in something.. was a polygraph ever done on him? When I saw the interview where I discovered he was a cop & he's talking.. before the documentary even said he was leading the interview, it's the immediate thing that came out of my mouth.. I would absolutely love to know if he's taken a polygraph test.. not to mention the couple of interviews with the parents..think I'd love to see mom polygraphed as well..."have you ever molested your daughter?" Do you know what happened to your granddaughter?" "Did you ever hurt your granddaughter?" Did you inappropriateatly touch your granddaughter?"
