South Vietnamese General Nguyen Ngoc Loan, chief of the national police, fires his pistol, executing suspected Viet Cong officer Nguyen Van Lem (also known as Bay Lop) on a Saigon street on February 1, 1968, early in the Tet Offensive. Lem was suspected of commanding a death squad which had targeted South Vietnamese police officers that day. The fame of this photo led to a life of infamy for Nguyen Ngoc Loan, who quietly moved to the United States in 1975 and opened a pizza shop in Virginia.
