When you're in a hole, stop digging

I knew there was another reason I was dreading the aftermath of the Hariri assassination, and I just got a reminder of what that reason was: The instant hatching of a school of experts in incredibly arcane and unfathomable forensic science always makes me feel old.

Today's lesson: the physics of bomb craters. These photos prove beyond a shadow of a doubt that the explosive had to have been buried under the roadway (and not, as was temporarily posited, in another vehicle or roadside device). Or they don't. I must confess to limited experience in the creation and maintenance of craters, and will defer to the experts, who have determined that the hit was clearly done by the Syrians, the Americans, the Israelis, the Chinese, and possibly the Krell.
