He is indeed a complete idiot as he knew it very well that he is in a hostile country but still he did this stupid act.
A US student was arrested in North Korea for stealing a little banner with a political slogan. There is a full version of this video where he constantly apologizes and bows before every question. It's pretty funny what they did to him. Personally I don't feel bad for him, he is a complete idiot for doing that.
