While I sympathize with the defecting North Koreans, you're a little extreme in your description of the Chinese guards (and uniforms) - just doing their job. At least they're attempting to maintain border security, and some law & order with illegal aliens in their midst. Makes me a little envious...
They're people who don't seem to want freedom for themselves, or anyone else. They aren't guarding against economic invaders. They're chicoms!
They are posted to keep North Korean political refugees and defectors out of the Japanese school. I won't make excuses for them. Sorry to be about 'extreme' about Freedom. I doubt if any of those who went over the wire last night on that video, if you and I sat down with them, would think of me as 'extreme' in my thinking or description.
