I now read the following from NKNews.org:
Matthew Miller grew up in the Californian town of Bakersfield, the son of petroleum engineers, and first visited Korea four years ago to stay with a brother stationed with the US Air Force where he found work teaching English.
Some of the newspapers and TV news in South Korea occasionally run stories vilifying "illegal English teachers" as a menace to Korean society. I wonder what they would do if they figure out Miller was...one of those?
