It's crazy, my father once got the chance to visit North Korea on a paid business trip, but he was asked to leave his cellphone, laptop, books, and mp3 player at the airport so he wouldn't contact anyone or spread any "propaganda" on his stay there. At this time he was a well respected business man world wide. He deiced it was too outrageous for someone of his status to be treated like a criminal and didn't *** up visiting after all.
