I have been following this case since the story broke on several sites, as well as NG and Greta, and I watched the video today of Tim suspending the search.
To me, Mandy's uncontrollable sobbing, was more than I would expect from a "seasoned" searcher. I can see a few tears as a result of stress, frustration, and disappointment at having to stop the search, but not as much as Mandy was displaying. Tim also looked pretty upset...rarely looking at reporters (head down), probably trying his best to keep his emotions in check.
I felt Mandy's sobbing was more cathartic than disappointment...cathartic in that they FINALLY found something critical to the case, and the emotions she and others have kept in check in order to do this search finally came out.
I feel strongly that the area that has been cordoned off needs to be excavated carefully by a forensic team, in order to preserve as much evidence as possible, as well as possible dental records and DNA matching, etc.
This is just my humble opinion...based on what I have read and watched about this case, and my gut feelings.
P.S. For those who have asked why it took LE so long to start looking for Caylee...I think it's because they didn't know where to start since none of the Anthony's are talking or giving out any credible or logical information. Where and how would you begin a search for an almost 3 year old girl if you didn't have any kind of starting point?
