I have to say I'm really curious about how intensive and how public this search is.
The last search was the one with ground-penetrating devices. Due to the extremely dismissive press event the next day, I really had the impression that day's search had been a show due to the outrage over Laura Babcock. "Look, we ARE taking this seriously, and we didn't find anything, so shut up. Also, she was an escort." (Needless to say I'm still irritated about that presser.)
But this one came out of nowhere, in the midst of relative quiet, and they are obviously allowing media to get up close and personal, or at least not trying at all to block the view from the road. And they are obviously throwing a lot of resources at it.
