Why not a lie detector

This girl has some serious issues, what kind of a mother refuses to help find her own child. Casey is maintaining her innocence, so why don't police push harder for a lie detector test. If this girl is really telling the "truth" than why not take the test to confirm her story about this alleged nanny. Even if the police cut a deal with her to ask only questions about the nanny it would at least help credit her story if she is telling the truth about the babysitter. This girl is defiantly a huge liar, but it may be possible that parts of her stories are rooted from the truth. The parents are in a very difficult spot, and my heart goes out to them, those protesters should really think about who they are hurting, it is obvious that Casey does not care, but they parents are the ones suffering. Leave the family alone, Casey is thriving off of all this attention, these protesters are not helping in the search for little Caylee. On the other hand the parents are not able to get answers from their daughter, so they should really think about letting their daughter sort out her own mess. This does not mean that they need to abandon her, but let her suffer through the lies she has told. This may be the only way that she will realize the severity of her actions and possibly let the truth slip out. Remember the boy who cried wolf eventually got eaten. I'm sure this girl will have a similar outcome. All the best to Cindy and George, you are in my prayers

Message to the protesters:
You all need to go home and be with your own families, if you are affected by this case and truly want to find this little girl, than join in the search, for every minute you are outside of the Anthony home, you could be a precious resource to the police in helping find this baby girl. It shows extreme distaste and low class to spend your time screaming outside the home. I am disgusted that some of you have brought children into these protests, and to those people doing this. Think about the danger that you are putting your own children in. There has been violence, foul language, and yelling. This is child abuse, you are a risk to your children, what if they get hurt? I am sure that you all have better things to do, like hold your kids in your arms, you gotta think "at least you still have them"
