That photograph is unbearable because it traps a man in the exact second before his murder. He is alive, kneeling, terrified, and fully aware that the next sound he hears will be the gunshot that ends him. The camera steals even that last mercy, forcing him to die forever, over and over, every time someone looks. He is not a symbol or a lesson, he is a human being caught at the instant the world decides he no longergets to exist.
Ice are nazis. Abolish ice.
