DIED. NGUYEN NGOC LOAN, 67, South Vietnamese national-police commander whose 1968 point-blank execution of a bound Viet Cong prisoner in Saigon stunned Americans when they saw it on film; in Burke, Va. The widely reprinted photo, which won a Pulitzer Prize for Associated Press photographer Eddie Adams, fortified public opinion against the war. After the fall of Saigon, Loan and his family moved to Virginia, where he ran a restaurant. (See Eulogy below.)
Eulogy
By EDDIE ADAMS
won a Pulitzer Prize in 1969 for a photograph of one man shooting another. Two people died in that photograph: the recipient of the bullet and GENERAL NGUYEN NGOC LOAN. The general killed the Viet Cong; I killed the general with my camera. Still photographs are the most powerful weapon in the world. People believe them, but photographs do lie, even without manipulation. They are only half-truths. What the photograph didn't say was, "What would you do if you were the general at that time and place on that hot day, and you caught the so-called bad guy after he blew away one, two or three American soldiers?" General Loan was what you would call a real warrior, admired by his troops. I'm not saying what he did was right, but you have to put yourself in his position. The photograph also doesn't say that the general devoted much of his time trying to get hospitals built in Vietnam for war casualties. This picture really messed up his life. He never blamed me. He told me if I hadn't taken the picture, someone else would have, but I've felt bad for him and his family for a long time. I had kept in contact with him; the last time we spoke was about six months ago, when he was very ill. I sent flowers when I heard that he had died and wrote, "I'm sorry. There are tears in my eyes."
