Operation Big Switch and Korean Prison Interrogations

The CD is labeled "Korean War Interrogations 1952-1953." Most of this recording is in Korean making the context of it difficult to understand. Track one is in Korean. Track two is in Korean. Track three is partially in English, explaining that the recording was made in the Yondong Tho (?) Prison just after the Korean War, during Operation Big Switch. The prison was separated into two sides, with about 2000 prisoners on each side. The recording that follows are noises and singing from the prison. [The speaker says that Operation Big Switch was in 1952, but it was in fact in 1953.] Track four is introduced in English but it mostly sounds like western music with Korean singing.
