I don't get all this lying for each other... Is this just not odd, why incriminate yourself by lying?
Steve Croes went to police to tell them he saw the trio drop natalee off at the holiday inn. Why do this? Is their buddy system this tight that they would be willing to lie for each other even when they had nothing to do with Natalee missing?
Something more plays into this... maybe blackmail by the Sloot's (Deepak and Croes drug dealers? - Sloot's know this?)
