TES, and Tim Miller in particular, do not owe the members of websleuths anything. I've fought saying anything when reading some of the rather vitriolic comments people choose to post. The fact of the matter is, his organization doesn't make promises of finding someone. They are in the "hope they find someone" business, utilizing the best tactics they can. I cannot believe that there have been some who feel his leaving means he's leaving Caylee to fester and rot. Someone else did that.
Every comment I have seen Tim Miller make with regard to Caylee's disappearance has been with the hope that, in the limited time he can give her, that they can find her. I have been impressed that he finds ANY time at all. He sticks to the places of interest for the police. He stays on task. He does what he can do.
I am disappointed in those who would have any anger toward TES or Mr. Miller at all. Dare I say, ashamed of them.
