I fail to see where that's a suspicious coincidence. Weren't there many, many more coincidences that tie KC to the death of Caylee?
It was the Anthony's meter reader because a lazy and arrogant FCA dumped Caylee so very close to the Anthony's home, and the meter reader, doing his rounds near their house, had to take a leak.
It would be odder if Anthony's meter reader had found Caylee 100 miles away in a swamp, not where he did, but it still would have been a coincidence, not a conspiracy, for goodness sakes.
How much stranger it seems to me that anyone's theory of what happened involves blaming a peeing meter reader. Geez.
