Snipped, and BBM.
Exactly. Asking someone to provide fingerprints for exclusion is vastly different that being asked by LE to provide the clothing you claimed to be wearing when you stated you had been at the scene of a murder investigation a few hours before the victim's death. It is also vastly different than being asked to take a polygraph to determine the truthfulness of your version of events. If you're being asked to take a polygraph, even voluntarily, someone thinks you could be (ok, they think you ARE) lying about something very, very important. That's why they're colloquially called "lie detector tests". Suspects almost always lie about their participation in crimes, especially murder. Sometimes innocent people collaterally involved lie, too, but not as often. Particularly in murder cases, where the consequences are severe. That usually motivates truth telling. Of course, polygraphs are inadmissible in court. But they are still a very, very effective tool for LE to use when evaluating suspects. And suspect's responses to being ASKED to take one, I think, ARE admissible as evidence, as well as being very helpful to investigators.
And if Nina hadn't been INSIDE the mansion for a couple years, why would they need her hair samples? Is that another reason she told the, IMO, very odd version of Rebecca hugging her? To explain any hairs found on Rebecca? But then Rebecca was nude when she died, and may have just had a shower. Or was it because LE was gathering hair evidence at the scene? That seems most likely to me.
I've always found it intersecting that Nina added in the unnecessary detail of her yoga pants being NEW. There would be no way to determine if the pants she surrendered were the same as the ones she claimed to be wearing when she was at the mansion, particularly because the web designer eyewitness saw a woman dressed differently that didn't meet Nina's description. And NEW clothes would not have evidence of normal wear. The "new yoga pants" detail has always struck me as too much detail for the circumstances and the question. It's not just a self- centered comment-- it strikes me as untrue, the way liars typically add extraneous info to make something sound "more true." Same with that "pink Coach wristlet." It sounds like a well rehearsed part of the story she told. She wasn't just wearing clothes and carrying a handbag. KWIM?
I'm also glad Nina chose to give that in-depth interview. She didn't have to do that. A lawyer probably would have advised her not to give it, because it only adds to the impression that she had motive and opportunity. And that she was considered a suspect by LE (though officially unnamed to MSM).
If LE is collecting your DNA, your hair, your fingerprints, your clothing, and asking you to get scheduled for a polygraph, you ARE a suspect, whether named or not. And a prudent innocent person would get a lawyer right away, IMO. A guilty person should have one at that point, too, IMO.
