The man in the picture I spoke of was a Viet Cong Lieutenant that had just murdered a South Vietnamese Colonel, his wife and six children. Found in the act, five minutes prior to the picture being taken.
The person with the pistol is a South Vietnamese General. The General's name is 'Loan' and the photographer apologized to the General, several times during the rest of the General's life, for 'stealing his honor'.
The General was 'spot on' 'caught in the act', but sure as shit, he wasn't guilty of murder. Or anything else, other than taking out the trash.
PS Sweeping floors? I was in the next room scrubbing toilets.
