This is a no win situation for both sides.  He committed a crime in North Korea, we can not state this was not a crime based on our system.  I'm not happy about the outcome, I do not nor does anyone else know the full story.  You visit foreign countries, you are under their law, to ask the U.S. to step in and save you, is foolish.  I've have lived overseas, let me state this, how many of you know that living on a military base overseas, that the base is foreign soil, not U.S., how many know you can get married on that base, but it is not legal, you must go to the foreign embassy which is U.S. soil to make the marriage legal.  Naval bases the only place that it is U.S. Soil is a Naval Ship and if your not of age to service aboard it will not help you.  So say all you want about these countries, your at fault if you do not know their laws.  How would you feel if they  broke our laws, you will feel they must serve the time.  So best you back off and look at this situation more closely.
