I wouldn't wish what happened to poor Otto on anyone. Having said that, using a little common sense would tell you that North Korea is not a tourist destination. I feel terrible for his family and for what he went through, but hell's bells, why would any sane human being visit North Korea?
That was before he was harmed. My question like Linnster's, is why would anyone with good sense visit North Korea. It makes no sense at all.
When one 'tours' places like North Korea, Iran, Iraq, Syria, Afghanistan, etc., one should understand that the area is NOT safe. Warmbier found that out when he was arrested. BUT, that does NOT excuse the brutal treatment Otto received at the hands of the NK Government and they should be held fully responsible!
