The question of the polygraph?

[Mrs. B]

Mr and Mrs McCann, both 39, said last night that they were prepared to take a lie detector test if requested by the Portuguese authorities. “Kate and Gerry are happy to do anything that will help them to clear their names,” a source close to the couple said. “They have said all along that they want to cooperate fully with the Portuguese police, but as of today they have received no such request.”

So the  'offer'  was nothing more than empty posturing, wasn't it  ?

[Mrs. B]

Fact remains, they were telling the truth, & those who accuse them of lying about this has once again been proven to be liars themselves.

OK Red - knowing that Lie detectors are not 100% accurate, and some people can even beat them,  -  with hand on heart tell us what you would say if the McCanns took one and passed. 

(I'll take a guess that you won't give a straight answer to that question.)

irrelevant to my point, no one who takes such a test has the right to impose conditions, its preposterous..but that is what clarence mitchell does for a living, be preposterous, .but like the tapas 7 trying to guarantee conditions before they hauled their backsides back to pdl to do a reconstruction, no leaving no stone unturned there as they promised were they??... to answer your point, i would, like most people, accept the results, with the small proviso that sometimes they are wrong

[Mrs. B]

And WHY would they take a lie detector test, if they haven't been asked by authorities & knowing that the results aren't valid in court?

To placate the hounders? No, sorry, simply not worth it.

Kate refuses lie test Sunday Express (no longer online)

KATE McCann has done a U-turn over plans to take a lie detector test about daughter Madeleine's disappearance.

She and husband Gerry offered to undergo a polygraph examination in September to clear their names. They hoped it would help to clear up any doubts about their involvement.

Sources close to the couple made it known they were willing to be questioned after Kate was officially declared an "arguido" or official suspect in the case in Portugal.

But despite being approached by a leading UK polygraph expert, mother-of-three Kate, 39, turned down the chance. Don Cargill, chairman of the British And European Polygraph Association, said he was "shocked" by her decision.

Mr Cargill, official lie detector expert on TV's Trisha Goddard TV show, said: "I spoke to the McCanns' people and they came back with a list of conditions that would have been impossible to satisfy.

"They wanted me to prove the test would be 100 per cent accurate, that I was the world's best examiner and that it would be admissible in a Portuguese court – but I could not guarantee any of those things. Although polygraph testing is very accurate, it is not infallible."

Lie detectors work by measuring physiological responses such as blood pressure levels, pulse rate, breathing and sweat gland activity in the skin during questioning.

Any significant difference in these rates as the subject answers may indicate they are lying.

The process has been criticised but The American Polygraph Association says the current computerised technology is 98 per cent accurate.

Lie detector tests are not admissible in British or Portuguese courts, but a positive polygraph result from Kate would prove a useful weapon for the McCanns against smears by the Portuguese police.

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.

"I don't think it was the McCanns' fault. I was left with the impression the whole thing was a PR exercise to get sympathy at a time when Kate was under increasing scrutiny."

Mr Cargill believes if the McCanns were to change their minds, now is the time to do it.

Tomorrow marks 200 days since Madeleine, from Rothley, Leics, vanished from the family’s holiday apartment in Praia da Luz.

He said: "In the immediate aftermath of Madeleine's disappearance, feelings would have been running too high. But now Kate is back in England and has had more time to come to terms with things, the timing would be perfect."

Clarence Mitchell, the couple's spokesman, dismissed the idea, saying: "Of course they are not going to take the test. It's inadmissible in Portugal and there are doubts about the accuracy.

"Gerry and Kate don't need to do one as they are telling the truth."

So the  'offer'  was nothing more than empty posturing, wasn't it  ?

precisely, why did they even say they would be willing to do one in the first place if a) no one asked them let alone the police b) not valid anyway and c) set conditions on such a test

Nonsense

Eta seems one of their* friends *dropped them in it here reading that article again

[Mrs. B]

Irrelevant, as they only said they'd do a lie detector test IF asked by Portuguese authorities, nothing else.

of course you have the cite for that, and yea, why WOULD the police ask for one when its non admissable, more smoke and pathetic mirrors

And again..

And WHY would they take a lie detector test, if they haven't been asked by authorities & knowing that the results aren't valid in court?

To placate the hounders? No, sorry, simply not worth it.

May be they regret it now. In fact they proposed it and then escaped it, not politically correct.

[Mrs. B]

Why would they? They said they'd take a lie detector test IF THE PORTUGUESE AUTHORITIES REQUESTED IT - nothing else. They did not refuse to take a lie detector test - this is a case of a missing child, not the Jeremy Kyle show.

Don't tell me they ignored the Portuguese authorities would never request a test they considered as not reliable.

[Mrs. B]

There you go then, they weren't asked by police, so they never refused to do a lie detector test.
