Aruba will convince the public that they just had no evidence of a murder & could not prove all these parties had anything to do w/her disappearance.
Much like all the unsolved crimes here in the U.S.
People's memories will fade and all will be fine in Aruba.
The picture you paint is bleak. Sad but so true as we know here in America with all the unsolved murders as you say. The only other thing that I can think of that would be worse ,were if Joran were to go on trial with a ton of evidence against him .Then they got a ''judge Ito'' type judge that was just in the thing for the publicity ! Joran gets off [walks free] and the mother has to live with the fact that her daughters murderer is walking free . [Like OJ] Can't figure out which scenario is worse. Poor mother of Natalee
