I personally think that is is important to show the world what the reality of normal working people in DPR korea looks like. The regime just ruined that country and the brainwashing is unforgettable. By the way, some time ago I read or saw a video about people in North Korea, who voluntarily work with some foreign journalists by filming the reality of north korea and then passing it to the journalists. I would give you a link, but I cannot really remember where I read it/heard it.
