“There is also violence by omission: By not following the example of Georg Elser and attempting to remove Hitler, good Germans were culpable for the effects Hitler had on the world. By not removing dams I am culpable for their effects on my landbase. There is violence by silence. I will tell you something I did, or rather didn’t do, that causes me more shame than almost anything I have ever done or not done in my life. I was walking one night several years ago out of a grocery store. A man who was clearly homeless and just as clearly alcoholic (and inebriated) approached me and asked for money. I told him, honestly, that I had no change. He respectfully thanked me anyway, and wished me a good evening. I walked on. I heard the man say something to whomever was behind me. Then I heard another man’s voice say, “Get the fuck away from me!” followed by the thud of fist striking flesh. Turning back, I saw a youngish man with slick-backed black hair and wearing a business suit pummeling the homeless man’s face. I took a step toward them. And then? I did nothing. I watched the businessman strike twice more, wipe the back of his hand on his pants, then walk away, shoulders squared, to his car. I took another step toward the homeless man. He turned to face me. His eyes showed he felt nothing. I didn’t say a word. I went home.”
