However, we all know that any calls made by Natalee while she was in stress that night are forbidden, probably by the Holloways/Twittys' lawyers, to be discussed publicly, so I am assuming that they had those tapes analyzed professionally too. The question is, would Aruban law even allow into evidence such expert witnesses who say that "this voice belongs to Natalee" and "This background garble has the exact sound patterns as Joran van der Sloot's voice"?
This case makes me really rethink staying in other countries unless you know their legal system. I know Mexico's and I am not going there.
