I began dealing with subject matter that addressed the ongoing nature of human violence several years before the attack on The World Trade Center. After 9/11, I started to use maps, bar graphs, and satellite photographs. It was seeing the children’s drawings in the memorials for 9/11 that began their use in the paintings. They are primary evidence, a witnessing, but are also fragile and transitory. Like others of my images there is a duality as they present both innocence and violence.
