It was uncanny. You press a button and a man drops dead a hundred meters away. It seemed hollow and remote, falsifying everything. It was a trick of the lenses. The man is an accurate picture. Then he is upside down. Then he is right side up. You shoot at a series of images conveyed to you through a metal tube. The force of a death should be enormous but how can you know what kind of man you've killed or who was the braver and stronger if you have to peer through layers of glass that deliver the image but obscure the meaning of the act? War has a conscience or it's ordinary murder.
