Ummm...statistically that's one graffito. But close to three million attended his funeral. Over 56 were just trampled as a crowd effect. That should tell you what's really going on with the numbers.
Imagine Iran assassinating the head of the Joint Chiefs of Staff while he was in England, for an analogy. You wouldn't accept in peacefully even if you didn't like the pentagon, you'd call it the illegal assassination it was.
Yeah, you might get a graffiti painter somewhere, but that'd probably be about it.
