I would as to me it would be the natural thing to do if you knew you were not involved in anything.
Especially the situation they found themselves in. I would be appalled to think I was a suspect in what happened to my daughter.
The so-called abduction would also be credible IMO.
Just out of curiosity how many on here would refuse to do one if they were in the mccs position.
According to the Sun the question arose because;
"Thousands of Sun readers wanted to know why they had not taken a polygraph test over missing daughter Madeleine, four."
https://themaddiecasefiles.com/we-ll-do-lie-test-the-sun-21-09-07-t3058.htmlThere's no explanation of how the Sun were contacted by these thousands of readers, and I can find nothing in previous editions which mentions the subject. Armed with this 'fact', however the Sun managed to get a quote from an unnamed source;
“If they were asked to take a lie detector test by police, they would.
“They have said all along that they want to co-operate fully with the Portuguese police but, as of today, they have received no such request from the Portuguese authorities. Kate and Gerry are happy to do anything that will help clear their names.”
https://themaddiecasefiles.com/we-ll-do-lie-test-the-sun-21-09-07-t3058.htmlThe source immediately restricts the circumstances under which they would agree to take a test; only if the police were involved. As neither the UK nor Portuguese police used the tests because they were inadmissible in court, that wasn't going to happen.
Those thousands of Sun readers asked a question (allegedly) and got an answer. Kate and Gerry were not happy to do
anything to help clear their names. They had conditions. End of story.
