Have we even discussed this yet? RK had a metal rod with him, collected by LE (page 18 of this document: http://www.cfnews13.com/uploadedFiles/3464-3513redacted.pdf). Sounds just like the PI, who also used a metal rod, poking and probing the same area. I realize that it's a water meter reader rod, but I find it interesting. So that means that he was using the rod to locate Caylee, he wasn't out there to pee. I thought RK was in the clear, but this kinda makes me rethink LP's daisy chain theory. If he used the tool for work, fine, but why would LE want it? Because he was digging around near the body.
