Noddy, I agree about the lie detector test...why hasn't it been taken? It would surely be a good thing if it took some of the negative speculation away from the McCanns.
I'm not sure if this is correct but is there not evidence to suggest that most crimes are perpetrated by close family? I don't think this in a personal manner regarding the McCanns, but surely if it is so high a probability it's not surprising that a lot of people suspect their involvement somehow.
Taking the lie detector thingy would help, that is as long as it is reliable and they are not involved. So I can't understand why they haven't taken it.
