Prisoners in Tiger Cage in Vietnam

(Original Caption) This is one of the "tiger cages" used to confine political prisoners in South Vietnam, according to Thomas Harkin, the lone staff member of a House fact-finding team that toured Southeast Asia. Harkin and two congressmen said they found the "tiger cages" in a prison on Con Son Island, 60 miles off the South Vietnamese coast. Conditions were described as "shocking." Harkin has resigned, charging that the committee majority tried to suppress the findings.
