These accounts are strikingly different. I'm sure the true lies somewhere between "he was locked up in a safe room with a sawed-off shotgun" and "all you had to do was ask".
I don't really know about that dumb waiter though. It certainly does not look like the entrance to a safe room and I'm not even sure Kim could fit through it.
I think another aspect to consider is that even as someone as controversial as Kim you don't expect to get raided by a helicopter flotilla. It even somewhat surprises me that he didn't had a more solid defense built up, e.g. at least a 24h guard staff.
The "terrorism" aspect is quite easy to construct. There are a bunch of pictures around with him holding a gun and some even having an (inflatable) tank in his garden ( http://imgs.sfgate.com/n/p/2012/01/31/c007af25-a097-4eda-839... ). In today's over-terrorism craze situations like these make a good case to finally make use of all the overstocked terrorism gear and demonstrate its usefulness.
