Nonsense. Wrongly accused people most certainly need the best lawyer money can buy!
and *rightfully* accused people take on lawyers too, you dont know which way it cuts do you? Wasnt susan smith oj simpson caylee anthony and all those where its sure they were guilty
wrongfully accused innocent people tend to answer questions, take lie detector tests too, and not say they will take them only if its on their terms LOL who r u kidding
The McCanns and The Polygraph
In the Kate Prout murder case, the failure of Mr Prout to pass a Polygraph test led ultimately to his confession to the murder of his wife.
Back in September 2007 the McCanns, as part of their PR 'fight back' against the action of the Portuguese police in making them arguidos, made it known - albeit through the inevitable use of a proxy 'friend of the family'/'source' - that they would be willing to take a lie detector test to clear their names.
"They have said all along that they want to co-operate fully with the Portuguese police," the anonymous 'friend' stated, adding that they had "received no such request from the Portuguese authorities".
Once the frantic headlines, such as 'McCANNS: WE'LL TAKE LIE TEST', had been successfully embedded into the nation's newsstands, Clarence Mitchell, the McCanns spokesperson, stepped forward to pour cold water on the idea. Principally on the grounds that such evidence was not admissible in a Portuguese court.
And there the matter lay...
Until November, of the same year, when a "shocked" Don Cargill, chairman of the British And European Polygraph Association, spoke to the Sunday Express. He revealed that he had spoken to "the McCanns' people", with regard to taking a lie detector test, and they had come back "with a list of conditions that would have been impossible to satisfy".
Mr Cargill said: "Kate said she'd take it to prove her innocence but in reality, she wasn't willing. I was dumbfounded, to tell the truth."
The accompanying headlines, such as 'KATE REFUSES LIE TEST', were clearly unhelpful and so, as usual, Clarence Mitchell was afforded the final word on the subject:
"Gerry and Kate don't need to do one as they are telling the truth."
