Clint Van Winkle said this quote

the shooting and killing weren’t as black-and-white as most people think. The actions live in that hazy area of blown-apart stone walls and hesitations. Sometimes I shot when I shouldn’t have; other times I didn’t shoot when I should have. There was no way to explain why I did either. Everything happened so fast. Decisions had to be made. After I got home I began to see things in slow motion, see the actions that might’ve been mistakes.
