welcome back. as north korea tries to terrify the world, it's already terrorizing generations of its own people, locking parents, children, grandparents away in concentration camps. some lived their entire lives in these gulags, they are actually born into them, including a man who says he was born and raised in the notorious hell hole known as camp 14. he escaped to tell his story. before the break, you heard shin talk about seeing his brother and mother taken to the public execution site. that's where we pick up his story. >> translator: when i went to the public execution site, i thought that i might be killed. i was brought to the very front. that's where i saw my mother and my brother being dragged out. and that's when i knew that it wasn't me. >> how did they kill your mother? >> translator: they hung her. and they shot my brother. >> he speaks of it still without visible emotion and admits he felt no sadness watching his mother and brother die. he thought they got what they deserved. they had, after all, broken the prison rules. >> he believed the rules of the camp. >> this man is a veteran foreign correspondent who first reported shin's story in the "washington post" and later wrote a book about his life.
