This has been going on for 10 years now and still no answers, I feel as though this would finally put an end to the debate of whether or not the McCanns had any involvement with their daughters disappearance, I'm also sure a lot of people will agree with this and want it to happen, the McCanns have received more than enough tax payers money in fact, a rediculous amount, when a lie detector should have been done as soon as it came to light about them leaving their child alone to go out drinking, at the end of the day, the evidence stacks up against them, and if they are as innocent as they say they are, they would have no problem doing said lie detector
