I just watched this tech-talk video "BORN AND RAISED IN A CONCENTRATION CAMP" about a man who lived the first 23 years of his life inside a North Korean concentration camp. He escaped a few years ago.
When his mother and brother made an escape attempt (which failed), he was tortured for months about a possible family conspiracy. Then he was forced to watch them get executed. Now that he has escaped successfully but his father is still inside the camp, won't the guards torture and/or kill his father?
He talked about how his dearest wish is to see his father, and walk hand-in-hand down the street.
