Some of the claims in this article are rebutted by the book A Kim Jong Il Production (http://www.amazon.com/Kim-Jong-Il-Production-Extraordinary-K...), an excellent read. There is a lengthy discussion on how the book was sourced and a dedication to fact-checking and information accuracy. In it, they describe how many people inside actually do recognize their situation and how they're forced to act against how they feel. The crying at Kim Jong Il's funeral, in particular, is addressed and the book mentions how North Koreans that didn't look sincere enough in their grief faced punishment.
