In this image it presents a slight disturbing tone due to the photo having no colour and the fact the image was taken just before the execution of Nguyen Van Lem. The photo represents what Vietnam was like around 50 years ago and shows the effect of the Viet Cong on Vietnam.
The police chief named Ngoc Loan seems to show no emotion when pulling the trigger to the suspected Viet Cong member, however the Vietnamese soldier in the background of the image seems to show a face of distress like he’s trying to stop the police chief from killing the suspect.
