I don't think there are any other reasons for Tim pulling out right now. If they did find something, LE would be all over it and there would be helicopters in the air from various news organizations to cover it, imo.
I would assume the emotions from people you saw were because they didn't find Caylee. It has to be gutwrenching for them to know that she is still out there after searching for days on end. They want nothing more than to find her.
If it is in a remote location, the could have the roads closed way before where they actually are so no one can film back there and they can take their time and concentrate. And with FBI involved, they could restrict airspace over the search are to just LE.
