The question of the polygraph?

[stephen25000]

they had the intelligence not to do it...unlike those on the Jeremy Kyle show...which is where Lie Detectors belong

No dave, they feared it.

[Eleanor]

If taking a Polygraph is the only way of moving a case forward then I despair.

[Mr Gray]

No dave, they feared it.

stating opinion as fact as usual....if you did any research you would find that lie detectors can be very inaccurate in giving false positives for innocent people....only an absolute idiot would have taken the unreliable...unproven test

[Mr Gray]

No he was convicted and jailed for life without the body. He was still claiming he was innocent in jail and after he failed the lie detector he confessed and showed where he had hidden the body.

Debbie Garlick who began dating Prout a year after he murdered Kate had launched a campaign to win his freedom.

Prout had nothing to lose and everything to gain...he probably felt he could beat the test...it isn't difficult evidently

Again, you don't read, as per usual.

They are used as part of an investigation, not the be all and end all.

Polygraphs can also reveal liars.

It is not a one way street.

He didn't manage it though, did he?

[Mr Gray]

He didn't manage it though, did he?

no he didn't but it is evidently not difficult with the right training. That's why the result of a test would not prove anything ...It certainly would provide no evidence of the McCanns innocence

If you are getting nowhere with certain suspects because they refuse to answer questions then I believe a lie detector should be used in those circumstances. You have to be in control not them. They don't answer questions because they are scared. Now here's a lie detector test for you for being uncooperative  %£&)**#

I know nothing about polygraphs but I do know that lying is a complex matter. As I said on another thread, [moderated]s pick their victims with care and they target those who want to believe. Similarly the wife who wants to believe her husband is faithful will ignore evidence to the contrary until it becomes too much. Lying to large groups such as TV audiences is more difficult because the audience is unknown. Politicians are often trained to avoid direct lying for that reason. They learn how to give ambiguous answers and how to answer the question they want to answer rather than the one asked. A polygraph operator would ask direct questions and wouldn't accept diversion, so much more difficult to deal with imo. Innocent or guilty it's too much of a risk.

How do you force them to take it?

[Jean-Pierre]

How do you force them to take it?

You cannot be forced to take a polygraph test.  For obvious reasons.

[Alice Purjorick]

What precisely is your problem with what I have written?

I have no "problem" with what you have written at all.
I find it funny in both senses of the word and cannot take it seriously.

[Eleanor]

Thought not.

Thank you, Jean Pierre.

[faithlilly]

Thought not.

Thank you, Jean Pierre.

I'm surprised you had to have that verified Eleanor.

In this instance we are not talking about forcing the McCanns to take a polygraph but them willingly taking one in order to refocus the investigation.

It wouldn't refocus the investigation.  The McCanns are innocent and Scotland Yard knows this.
