Here is what I think about the polygraphs and RMC. Neither of these 2 had any reason to trust the polygraph machine, they don't know anything about these things. People with a history or drug abuse, adults living with minors, people who are in the drug culture, ex issues and have guns in their homes are not the types who typically trust LE. MC was partying the weekend away with common criminals, surely not the thing anyone wants to admist too or be asked about. But, they trusted LE and volunteered to take the polygraphs. Why would this be? Because they think they can "pull one" on the polygrapher or because they are telling the truth?
They aren't the types to think they can pass a polygraph while lying.
They were both asked re HaLeigh: "Did you kill her? Did you cause her disappearance? Her death? Do you know who did? Do you know where she is? " etc., etc.
RC said he was told he passed. MC said she was told she passed at least on the issue of her being home that night - she was. I think this is the only time she mentioned the polygraphs. The polygrapher knows immediately if the subject is telling the truth or not in response to questions. The result may have been discussed in their presence. Whether LE told them the truth of not, we do not really know. RMC are only repeating what they were told.
If they were deceived by LE, what is the point? To make them think they are home free and maybe they will mess up somewhere? I think it would be a better lie to tell them the polygraphs were inconsistent, or detected lying and watch their respones.
I think they were told the truth. They passed their polygraphs.
You make a lot of statements which I find questionable in this post and would like some clarification from you, if you please:
1. How do you know neither Misty or Ronald knows anything about polygraph machines?
2. Are you stating that Ronald and Misty are into the drug culture?
3. They were asked to take the polygraph, and agreed when asked. That isn't volunteering. That is complying. However, that in itself is not a presentation of a truthfulness. It is merely a statement of cooperation. So how do you know whether they are the types to think they can pass a poly while lying? Only someone who knows them personally could make that statement, and even then, must be very sure of them to be able to assert with such a statement.
4. How do you know what questions they were asked? An assumption can be made that they were asked similar questions to what you present, but you are stating this with such a matter of fact manner that I wonder how you know it for certain?
5. Misty's statement is "I was home because the test said I was home so I was home!" (close enough to the actual quote but probably a little paraphrased). She doesn't say she passed. She says the test said she was at home.
6. As to why would LE deceive them, it is not up to LE to have to deceive them. It is an interpretation on the part of Ron and Misty that they passed if they are told that LE is "satisfied." I would say that is the vaguest word toward "telling the truth" as it is "They're lying and we're satisfied we're dealing with a couple of liars." The interpretation is in the listener, not in what LE says. All we have is that they are "satisfied." No one is aware of what exactly they are satisfied with, and I've stated two of the possibilities. Nothing can push toward one or the other without clarification from LE, not even Ronald and Misty's assertions that they interpreted it as they passed.
7. It can equally be determined that LE gave them a false sense of security because they determined they were liars and wanted to watch how the story changed. Which, as we all know, has. Several times.
