A Popular Democracy
The BBC has broadcast a documentary alleging that North Korea used gas chambers to test new chemical weapons on human beings. A Guardian story on the documentary notes:
Defectors have smuggled out documents that appear to reveal how methodical the chemical experiments were. One stamped 'top secret' and 'transfer letter' is dated February 2002. The name of the victim was Lin Hun-hwa. He was 39. The text reads: 'The above person is transferred from … camp number 22 for the purpose of human experimentation of liquid gas for chemical weapons.'
Not surprisingly, given the rapprochement with the North, the South Korean government has cast doubt on the story, though it said it would have to investigate before arriving at any final conclusions–which basically means we can pretty much ignore its doubts.
